Question: What compilation series contains the album A Very Special Acoustic Christmas and features artists such as Tom Petty and the Heartbreakers? 
Context: A Very Special Christmas is the title of an ongoing series of Christmas music compilation albums that benefit Special Olympics.  It features songs performed by artists from a variety of genres, such as U2, Stevie Nicks, Jon Bon Jovi, Madonna, The Smashing Pumpkins, No Doubt, Whitney Houston, Run–D.M.C., Jason Mraz, Willie Nelson, Bruce Springsteen and Tom Petty and the Heartbreakers. "Make It Better (Forget About Me)" is a song written by Tom Petty of Tom Petty and the Heartbreakers and David A. Stewart of the Eurythmics.  It was released in June 1985 as the third single from Tom Petty and the Heartbreakers' 1985 album "Southern Accents". "Stop Draggin' My Heart Around" was the first single from Stevie Nicks' debut solo album, "Bella Donna" (1981).  The track is the album's only song that was neither written nor co-written by Nicks.  Written by Tom Petty and Mike Campbell as a Tom Petty and the Heartbreakers song, Jimmy Iovine, who was also working for Stevie Nicks at the time, arranged for her to sing on it.  Petty sang with Nicks in the chorus and bridge, while his entire band (save Ron Blair, whose bass track was played by Donald "Duck" Dunn instead) played on the song. Hypnotic Eye is the 13th studio album by American rock band Tom Petty and the Heartbreakers, released on July 29, 2014, by Reprise Records.  The album debuted at number one on the "Billboard" 200, becoming the first Tom Petty and the Heartbreakers album to ever top the chart.  "Hypnotic Eye" was nominated for the 2015 Grammy Award for Best Rock Album. Mojo is the 12th studio album by American rock band Tom Petty and the Heartbreakers, released on June 15, 2010 on CD and June 29 on BD.  It is Petty's first album with the Heartbreakers in eight years.  "Mojo" debuted at number two on the U.S. "Billboard" 200, selling 125,000 copies in its first week of release.  The album is also the band's first full album with bassist Ron Blair since 1981's "Hard Promises", as he played on only two tracks on the previous Heartbreakers album, "The Last DJ". Greatest Hits is a compilation album by Tom Petty and the Heartbreakers, released in 1993.  It is Petty's best-selling album to date and was certified 12× platinum by the RIAA on April 28, 2015.  The single "Mary Jane's Last Dance" became one of Petty's most popular songs, reaching #14 on the "Billboard" Hot 100 and #1 on the Billboard Mainstream Rock Tracks chart.  The other new song on the album is a cover of the Thunderclap Newman hit "Something in the Air".  The album contains no songs from 1987's "Let Me Up (I've Had Enough)".  However, three songs from 1989's "Full Moon Fever" were included; despite the album's technical status as a Tom Petty solo album, it contained contributions from several members from the Heartbreakers, thus legitimizing its inclusion on this compilation.  s of September 2011 , "Greatest Hits" had sold 7,464,000 copies in the United States, making it Tom Petty's best-selling album. Tom Petty and the Heartbreakers are an American rock band from Gainesville, Florida.  In 1976, the band's original lineup was Tom Petty as the lead singer and guitar player, Mike Campbell as the lead guitarist, Ron Blair on bass, Stan Lynch on drums, and Benmont Tench on keyboards.  The band has largely maintained this lineup, with a few exceptions.  In 1981, Blair, who was tired of the touring lifestyle, left the band.  Blair's replacement, Howie Epstein, stayed with the band for the next twenty years.  Scott Thurston joined the band as a multi-instrumentalist, mostly rhythm guitar and second keyboards, in 1991.  Blair returned to the Heartbreakers in 2002, the year before Epstein's death.  In 1994, Steve Ferrone replaced Lynch. A Very Special Acoustic Christmas is the sixth in the "A Very Special Christmas" series of Christmas music-themed compilation albums produced to benefit the Special Olympics.  The album was released in 2003 by Lost Highway Records.  As opposed to earlier editions that contained a wide variety of musical styles, this version of A Very Special Christmas featured primarily Country and Bluegrass artists. Highway Companion is the third solo studio album by American singer-songwriter Tom Petty.  It was released on July 25, 2006, and charted at #4 on the "Billboard" 200 album chart.  The album was produced by former Traveling Wilburys bandmate Jeff Lynne, who also produced Petty’s highly acclaimed first solo album, "Full Moon Fever", as well as the Heartbreakers' next album "Into the Great Wide Open".  Petty released the album through Rick Rubin's American Recordings label and Warner Bros.  Records, where Petty has had a record contract since his second solo album, "Wildflowers" (which was produced by Rubin).  The tracks "Saving Grace" and "Big Weekend" were released July 4, 2006 on the iTunes Music Store.  It ended up being Petty's only album for American Recordings, as that label moved to Columbia Records distribution in 2007; Warner Bros. retained the rights to Petty, eventually reassigning him to subsidiary label Reprise Records. "Mary Jane's Last Dance" is a song written by Tom Petty and recorded by American rock band Tom Petty and the Heartbreakers.  It was recorded on July 22, 1993, while Petty was recording his "Wildflowers" album, and was produced by Rick Rubin, guitarist Mike Campbell, and Tom Petty.  The sessions would prove to be the last to include drummer Stan Lynch before his eventual departure in 1994.  This song was first released as part of the "Greatest Hits" album in 1993.  It rose to #14 on the "Billboard" Hot 100, becoming his first "Billboard" Top 20 hit of the 1990s, and also topped the "Billboard" Album Rock Tracks chart for two weeks.
