She is a three-time winner of the Canadian music industry Juno Award for Female Vocalist of the Year (1985–1987).

Most recently, her music has been featured on "Canadian Idol".  She continues to record music under her own independent label.

Till I Die (Machine Gun Kelly song): "Till I Die" is a song by American rapper Machine Gun Kelly.  The song premiered via YouTube, on January 5, 2015 and was released in the US on January 6, as the lead single from Machine Gun Kelly's sophomore studio album, "General Admission".  It contains references to artists from Cleveland, as well as to the life in the state of Ohio.  The song received positive reviews, with critics praising MGK's lyrical ability and inert references to Cleveland, describing the song as a "perfect trap anthem".  The song was produced by J.U.S.T.I.C.E. League when the song was recorded in 2014, and the group also handled the distribution of the song.  A new version of the song is also featured on the soundtrack for "NBA 2K16".

I Used to Work in Chicago: "I Used to Work in Chicago" is a drinking song.  It was written by songwriter and entertainer Larry Vincent.  The earliest printed date for the song is March 1945 in the underground mimeographed songbook "Songs of the Century", however versions of the song circulated "on the street" as early as 1938 according to the Digital Tradition Folk Music Database.  Many of the lyrics are considered humorous because of the oblique sexual references.  The song is often chanted by various British university sports teams, most notably from the University of Winchester Men's Hockey Team.

Shine (Gwen Stefani song): "Shine" is a song recorded by American singer Gwen Stefani, featuring collaborative vocals by American entertainer Pharrell Williams.  Originally intended for Stefani's band No Doubt, it was written and produced by Williams, with songwriting contributions from Stefani.  It is a reggae pop and ska song that is featured in the 2014 animated film "Paddington."  The lyrics revolve around the lead character Paddington Bear's journey to London and his identity crisis.  Stefani initially disagreed with Williams' choice to use direct references to Paddington in the lyrics, but praised this decision after watching the film with her children.  She reported that her involvement with the recording was inspired by her then-husband Gavin Rossdale and her children's connection to England.

My Brother the Cow: My Brother the Cow is the fourth album by the American grunge band Mudhoney.  It was released on Reprise Records on March 28, 1995 (see 1995 in music).  "My Brother The Cow" includes numerous direct references to bands that influenced Mudhoney's sound.  The song "F.D.K. (Fearless Doctor Killers)", for example, is a reference to the Bad Brains song "F.V.K. (Fearless Vampire Killers)".  "Orange Ball-Peen Hammer" alludes to the song "Orange Claw Hammer" by Captain Beefheart, as well as containing lyrics borrowed from Led Zeppelin.  "1995" is homage to the song "1969" by The Stooges, and also includes musical references to "L.A. Blues", another Stooges song.

The Entertainer (song): "The Entertainer" is a single by singer Billy Joel released as the only single from his 1974 album "Streetlife Serenade".  The song peaked at #34 on the US charts, a Top 40 hit for Joel that year.  The song is a cynical and somewhat satirical look at the fleeting fame of a musician and fickle public tastes ("Today I am your champion / I may have won your hearts / But I know the game / You'll forget my name / And I won't be here / in another year / if I don't stay on the charts"); this theme would be examined in the later song "It's Still Rock and Roll to Me".  Another verse in the song references the shortening of Joel's song, "Piano Man", from 5 minutes and 38 seconds to 3 minutes and 5 seconds to fit a radio slot, referenced by the lyrics "It was a beautiful song, / but it ran too long / If you're gonna have a hit, you gotta make it fit / So they cut it down to 3:05."  Additionally, the timing printed on the label of the 7" release of "The Entertainer" was 3:05, although the actual 45 length was 3:11 (while the album length was 3:41).  In the single version, Verse 3 (which starts at 1:02 in the album version) is edited out, and Verse 2 (which starts at 0:40) contains a steel guitar in its second half, which is actually featured in the second half of the "third" verse in the album version; indeed, on the single mix, the instrumental crescendo of the album version is anticipated by bringing the fuller instrumentation of Verse 3 under the vocals of Verse 2.  As a result of this, the slightly emptier original instrumentation of Verse 2 (which includes a downward slide on the synth) and the vocals of Verse 3 are completely omitted, while the instrumentation of Verse 3 (featuring the steel guitar) does appear, but earlier.

Radio (Alesha Dixon song): "Radio" is a song by English recording artist Alesha Dixon from her third album, "The Entertainer".  The song is "The Entertainer"' s second single, after "Drummer Boy" and was released on 28 November, coinciding with the album's release.  One of the remixes features rapper Wiley, a member of grime band Roll Deep, whom Dixon collaborated with previously whilst featuring on their single, "Take Control".  Dixon performed "Radio" for the first time on "Strictly Come Dancing" on 14 November.

Waiting for Superman (song): "Waiting for Superman" is a song co-written by Chris Daughtry for his band Daughtry's fourth studio album, "Baptized".  It was released as the lead single from the album on September 17, 2013.  The song's title and lyrics are references to the comic book superhero Superman and includes other references to the comic, including Lois Lane and Metropolis.

Piano Man (song): "Piano Man" is the first single released by Billy Joel.  It was released on November 2, 1973, and has been included on several subsequent albums.  Joel's first major hit and his signature song, the song peaked at #25 on the "Billboard" Hot 100 chart in April 1974.  In 2016, the Library of Congress selected "Piano Man" for preservation in the National Recording Registry for its "cultural, historic, or artistic significance."

Westside Story (song): "Westside Story" is the debut single by American rapper and West Coast hip hop artist the Game.  The song was produced by both Dr. Dre and Scott Storch, and was co-written by Mike Elizondo, Dre, Storch, the Game and 50 Cent.  It was released in 2004 as the lead single from Game's debut studio album "The Documentary".  The song debuted at #99 and peaked at #93 on the "Billboard" Hot 100.  It was an airplay-only release, thus no music video for the song was made.  Rolling Stone's review of the album described this song as "a kind of L.A. version of "In da Club".  The Game has stated that this song is a tribute to Tupac Shakur, with a direct reference to him, saying "I got +California Love+ fuckin' bitches to that Pac shit."  The Game also makes references to Tupac's songs, "California Love" and "Against All Odds".  Other references include: Nate Dogg, Tha Dogg Pound (D.P.G.) and their song "New York", Westside Connection, Michael Jackson and his album "Thriller", DJ Pooh and Kool G Rap.  There is a remix featuring Snoop Dogg singing the hook and a version with both Snoop Dogg and 50 Cent on it.
