This user has a limited history and is not a registered user, so I am replying here instead of on the talk page, where they sent me a note personally.  

The user mentioned Wikiproject Albums.  However, that project is not relevant to this page, since that policy applies to album articles (this is not) and in actually makes no comment at all about which albums should be included on an artist's article (I just read the page).  The policy that actually applies to this page is WikiProject Musicians, and it does not say anywhere that the article should include "all albums where Mayer is a primary contributor." (or any other artist).  The policy there is rough and incomplete.  Thus, I have been operating on precedent, as well as what makes the most sense and what is most fair to the works.  Works done by a band should be credited to the band as a whole, not an idividual, since that just isn't fair.  Additionally, Wikipedia has a long history of separating the discography of an idividual from that of the musical group they were/are in. Here a few examples: Jack White, John Phillips, David Ruffin, Sly Stone, Larry Graham, Nick Lachey, Brian Wilson, Tina Turner, Nicky Wire, Michelle Williams (singer), Mick Jagger, Agnetha Fältskog, John Entwistle, Vince Neil, Stanley Clarke, Robert Plant, Frank Black, Darren Hayes, Mark Burgess (musician), Anni-Frid Lyngstad, Graham Coxon, John Lennon, Steve Howe (guitarist), Neil Finn, Roger Daltrey, Smokey Robinson, Gladys Knight, Randy Bachman, Robert Wyatt, Biosphere (musician), Individual members of the Beach Boys, James Dean Bradfield, Joey Eppard, Steve Marriott, Grant McLennan, Tony Banks (musician), Sisqó, Alex Chilton, Bob Mould, Jim Capaldi and there are many more.

Many of these discographies have notes that wikilink to the appropriate article for the full band discograhy.  Therefore, in the insterest of consistency, that same model should be applied here.
