I thought the ranking part was implied given the account is at RATE Your Music
The volume. If it's all you do in your spare time, then I could see it as being feasible. But since you claim to have a social life (and a successful love life), I don't really think that's plausible. If you listen to music at work with no distractions, it's also plausible. I can tell you I can't listen to an entire album without being interrupted for something at work. If you can also listen to it without zoning out with work, then yes it's probably feasible. Being a supervisor, I can imagine it's difficult for you to listen to music for extended periods without interruption (if your employer allows that at all). I have no idea what your particular duties are for this position at this company, though.
I wish I were able to listen to thousands of albums and retain all of the aural details with minute precision like you claim. Unfortunately, I can't claim such a superhuman feat.
