Nothing you said sounded like you "knocking my job" but to clarify, I don't listen to music at work (well I have Spotify playlists I created specifically for the office- I'm the resident DJ- but that's just background noise basically).
If I'm checking out new stuff (which I actually haven't been doing much of lately), I listen to it while on the move (during my commute or running errands or on my way to meet up w/ people on the weekend) or sometimes at home. I probably average 2 full albums per week day (maybe more on weekends) and they're almost never in a single sitting. I generally don't have a Trung-style urge to devour as much new music as possible anymore but it's still nice to make these "to listen/watch" lists to file things away for a rainy day- why just rely on your memory when you can make a list?
Not familiar with what.cd (heard of it but never visited) but I guess a more interactive Discogs is pretty accurate (Discogs seems to be even more comprehensive for music but doesn't include film and nobody really cares about rating or reviews on there). You don't have to set up folders on RYM- once you rate something, you can search for it by genre as well as artist, title, release year and a few other ways. This makes it handy for Babble polls (favorite albums/movies per genre or album/movie of the year etc).
"Are different releases of the same music listed as separate albums?"
Not sure exactly what you mean but each album profile includes all available issues (vinyl, CD, alternate album art, reissues w/ bonus tracks etc) and the site often includes both US and UK releases of the same albums as separate entries if the tracklistings are different.
