The band was not sure how to release so much material, initially opposing suggestions of a double album citing both cost and a potential overload of too much music.
They indicated a likely plan to release a normal-length album, and save other songs for future shorter EP releases.
The band, however, ultimately settled on a 13-track physical album, with a second physical album entitled "Barenaked Ladies Are Men".
The latter album was originally pre-released exclusively in Canadian Starbucks locations on October 3, 2006.
This version of "Are Men" contained 12 of the remaining tracks, plus "Are Me"'s two singles.
The four songs not included on either of those releases were deemed as digital-download "bonus tracks" and it was implied that they were not going to be made available physically.
This was consistent with the "Deluxe Edition" of the "Are Me" album, which compiled the 25 tracks into a two-disc package that excluded the "bonus tracks".
However, when "Are Men" officially received widespread release on February 6, 2007, it contained all 16 tracks not on "Are Me", including the "bonus tracks"; This tracklist was not announced until shortly before "Are Men"'s release.
A bonus "All New Revue" CD was offered to fans if they preordered the "Are Me" album.
The CD contained the same 13 songs as the basic "Are Me" album performed live and acoustic at the Glenn Gould Theatre in Toronto.
A 5.1 surround sound deluxe edition of all 29 songs was released in the US on December 12, 2006, and alongside "Are Men" in Canada on February 6, 2007.
Fans were offered several additional format and content options for purchasing the "Are Me" session material.
The following is a list of all release versions of the "Are Me" sessions material: 
The first games containing a bonus stage are widely believed to be Namco's "Rally-X" (1980) and "Galaga" (1981).
In the latter, the level would begin with the text "Challenging Stage" and would feature enemies that do not attack.
The player is then rewarded extra points based on how many enemies could be eliminated.
Since few modern games use points as an incentive for gameplay, most modern bonus stages reward the player with power-ups rather than points.
Modern games have often blurred the traditional distinction between bonus stages and ordinary levels.
Most first-person shooter games allow players to enter bonus rooms within larger (non-bonus) levels to temporarily power up.
Some games have optional bonus stages which must be discovered and whose completion impacts the mechanics of the rest of the game, as in the "Star Road" levels of "Super Mario World".
There are bonus levels in most "Crash Bandicoot" games, save for "Crash Twinsanity" and "Crash of the Titans". 
The E.U.
Edition of the "Bachelor No.
2" CD on V2 Records has a rearranged track listing that removes "Driving Sideways" and adds a new track "Backfire".
The Japanese bonus tracks are included.
"How Am I Different" – 5:03  "Nothing Is Good Enough" – 3:10  "Red Vines" – 3:44  "The Fall of the World's Own Optimist" – 3:06  "Satellite" – 4:10  "Deathly" – 5:37  "Ghost World" – 3:30  "Calling It Quits" – 4:09  "Susan" – 3:51  "Backfire" – 3:25  "It Takes All Kinds" – 4:06  "Save Me" – 4:35  "Just Like Anyone" – 1:22  "You Do" – 3:43  "Save Me" (Video)
