You're the one making that argument! You're the one saying "performed by" on Quake means that's the main artist of the release.
We're saying, that's wrong. The performer is not the same as the main artist for the release. @Horican is exactly right about NIN albums. Here are the credits for TDS:
"writing, arrangement, and performance: trent reznor"
Is Trent Reznor the main artist for TDS?
