Context paragraphs:
(She's So) Selfish: "(She's So) Selfish" is a hit song written by Doug Fieger and Berton Averre that was first released by the Knack on their #1 debut album "Get the Knack" in 1979.  It also appeared on a number of live and compilation albums.  It was intended for release as a single, but was prevented by its "scatological" lyrics.  It was inspired by the same woman who inspired the band's #1 single "My Sharona."  It was praised by critics for its hooks and style, but criticized for its nastiness and sexism.

Sky (US band): Sky was an American rock power trio active in the early 1970s, based out of Detroit, Michigan.  It released two albums with RCA before breaking up in 1973.  It's mostly known today as an early point in musician Doug Fieger's career, later the frontman of The Knack.

Chrissie Hynde: Christine Ellen "Chrissie" Hynde (born September 7, 1951) is an American musician who is best known as a founding member of the rock band The Pretenders.

Normal as the Next Guy: Normal as the Next Guy is the 6th and final album released by The Knack in 2001.  It marks the 4th comeback attempt by the band after its second album, "...But the Little Girls Understand", failed to achieve the success of the band's début album.  Allmusic critic Mark Deming noted that the album finds songwriter and lead singer Doug Fieger having resolved his issues with women, but has not "found a subject that appears to compel him nearly as much as the treacheries of girls once did."  Therefore, Deming feels that compared to older songs by the band, the songs on "Normal as the Next Guy" "may be more pleasant, but they're not as interesting."  The "Rolling Stone Album Guide" gave the album a 3 star rating, as high as the group's début "Get The Knack", and higher than any other Knack studio album.

Packed!: Packed!  is the fifth album by rock group The Pretenders, released in 1990.  For this album, the only real member of the group is Chrissie Hynde; no other person is pictured anywhere within the album package, and a rotating cast of session musicians (rather than a set band) is used to back Hynde throughout, essentially making this a de facto solo album by Hynde, only using the Pretenders name to satisfy contractual obligations.  However, drummer Blair Cunningham plays on all tracks, though he is not credited as part of the band.

Last of the Independents: Last of the Independents is the sixth album by rock group The Pretenders, released in 1994.  For this album, the band is officially credited as being Chrissie Hynde (vocals, guitar), Adam Seymour (guitar), Andy Hobson (bass) and Martin Chambers (drums).  However, this line-up only plays together on one track ("All My Dreams"); the rest of the album is performed by Hynde and Seymour in conjunction with a rotating series of musicians on bass and drums.  These musicians include Hobson and Chambers, as well as bassists Andy Rourke, Tom Kelly and David Paton, and drummers Jimmy Copley and J.F.T. Hood.  A few other session musicians also appear, including Ian Stanley, and one-time Pretenders guitarist Robbie McIntosh, who plays alongside Hynde and Seymour on "I'm a Mother".

Can't Put a Price on Love: "Can't Put a Price on Love" is a 1980 song written by Doug Fieger and Berton Averre.

It was the second song from that album that was released as a single, reaching #62 on the "Billboard" Hot 100, falling short of the performance by its preceding single, "Baby Talks Dirty", which reached #30 in Cash Box and #38 in "Billboard".  Overall, it was the fourth single which The Knack had released, and was the first such release which did not reach the Top 40.

My Sharona: "My Sharona" is the debut single by the Knack.  The song was written by Berton Averre and Doug Fieger, and released in 1979 from their album "Get the Knack".
