The For Your Entertainment album was released in several versions including the original and deluxe U.S. versions, various international versions, a tour version, and the "Glam Box" version. I have not distinguished among the various versions except with the notation "bonus track" if it was not on the original album. For more detailed information, see Wikipedia.
 Adam was cast as Joshua in The Ten Commandments: The Musical that played at the Kodak Theatre in Hollywood, California. Adam sang six songs with other cast members and one solo song (see: Is Anybody Listening?). A DVD was released in 2006 starring the original cast (including Adam).
 Adam joined the national tour of the musical comedy "Wicked" as part of the ensemble cast and as an understudy for the role of Fiyero. The tour began in Toronto, Ontario (Canon Theatre) on March 9, 2005, playing there for about six weeks. The show moved on to Chicago's Ford Center for the Performing Arts for six weeks, then to the Pantages Theatre in Hollywood for six weeks, and finally to San Francisco (Orpheum Theatre) for yet another six weeks, ending on September 11, 2005. Adam later rejoined the Los Angeles production of Wicked from February 2007 to October 2008. As Fiyero, Adam sang Dancing Through Life with others in the cast and the duet As Long As You're Mine (although as understudy, he did not perform this role in every show).
 Adam co-wrote several songs during 2006-2008. During this time, Adam tried a variety of ways to market his music including performing at the Zodiac Show, working with an independent producer under the Digital Glitter label, posting "demos" on his MySpace page, and even performing in a rock band called The Citizen Vein. The band was comprised of Adam as lead singer, Monte Pittman and Tommy Victor on guitar and backup vocals, and Steve Sydelnik on drums. The band played at the Cat Club in Hollywood on 12/23/06 and 3/3/07, at the Knitting Factory in Hollywood on April 19, 2007, and at The Pitcher House in Hermosa Beach on May 12, 2007. When known, I've indicated where a particular song was performed, but I cannot find any information about exactly which songs were played at all events. See Footnote  for information on additional songs of this type.
 There was never a "Top 6" because during the first Top 7 week, the judges used their "save" to keep Matt Giraud from being eliminated. The next week, two people were sent home (Anoop Desai and Lil Rounds). I've referred to these two weeks as "First Top 7" and "Second Top 7."
 The Take One album is a compilation of songs Adam had recorded prior to American Idol while working as a session musician. At the time of the album's release, Adam issued a statement: "Back in 2005 when I was a struggling artist, I was hired as a studio singer to lend my vocals to tracks written by someone else. I was broke at the time and this was my chance to make a few bucks, so I jumped at the opportunity to record for my first time in a professional studio. The work I did back then in no way reflects the music I am currently in the studio working on."
 Adam recorded this song as a favor to Nick LaRouche (a skater whose partner was in Wicked with Adam). The pianist in this recording is Brian Perry (the music conductor for the LA production of Wicked).
 At Fantasy Springs, Adam surprised his fans by singing Whole Lotta Love in a slower tempo than the typical "rock" version he had sung throughout the American Idol Live tour. This acoustic version was a big hit and he continued to sing it in this manner through most of the Glam Nation tour (changing it up again with a more medium tempo in November).
 On 9/15/10 in Atlanta Georgia, Adam sang a reggae version of Whole Lotta Love in honor of Longineau Parson's last Glam Nation show as Adam's drummer. Longineau returned to his band Yellow Card and Isaac Carpenter took over as Adam's drummer at the next show on 9/17/09 in Melbourne, Florida.
 Technically, Adam didn't sing this song, but I included it because it was part of the medley.
 In June 2009, Hi Fi Recordings announced they were planning to release an album called On With The Show that included songs co-written by Adam and recorded before he went on American Idol. However, this album was not published once Adam released a statement that these songs were demos and not intended to be published. The two songs on the proposed track list that were not co-written by Adam (Want and On With the Show) were included as “bonus tracks” on the released album called Take One. See Footnote .
 The Acoustic Live! album was released December 6, 2010, and included acoustic performances by Adam recorded live earlier in the year.

The album was sold exclusively by the Adam Lambert Music Store on AdamOfficial.com. It sold out almost immediately so the store made a second run. The original run features a blue label on the spine of the CD case and is known as the Blue Label ediition. The second run features a red label on the spine of the CD case and is known as the Red Label edition.
 Beg for Mercy songs are apparently drawn from recordings of Citizen Vein songs co-written by Adam and Monte Pittman prior to American Idol. Adam tweeted about this album: "Beg For Mercy project is same as ‘Take One’. some songs I worked on 5 yrs ago and never finished. This release comes as a surprise to me… It is NOT what I’m currently working on, nor does it reflect my artistic vision. Some folks will do anything to make a buck. F*ck."
 Paramount Sessions features Steve Cooke, a Los Angeles-based rock musician. Similar to the Take One album released in 2009, this appears to be based on works-for-hire with Adam providing vocals for other writers’ music and Monte as a session musician. Adam’s name was used to market the album and Adam tweeted: "the paramount sessions is the same situation [as Take One]. I don’t even know who steve Cooke is. I think both projects were mastermind (but I mind) by Malcolm Welsford."
 The Trespassing album was released in several versions including the original and deluxe U.S. versions, various international versions, and a fan version. I have not distinguished among the various versions except with the notation "bonus track" if it was not on the original album. For more detailed information, see Wikipedia.
