I'm not sure about whether you were just QFE-ing me or actually replying to me, but I wasn't actually referring to the MP3 files when I said I browse by game. I meant I look up a specific game here on the site, maybe even a specific song from its soundtrack, and I listen to the remixes thereof, not knowing their genre beforehand, because I don't really care. As I remember it, the ID3 limitation of only one genre was not the reason for not allowing visitors to this site to search for remixes in a particular genre. It was an ideological design choice, it was one of the reasons for the VGMix exodus, and I'm pretty sure it was explained in the FAQ back in the day, along with why we weren't allowed to share favorites lists on the boards. I'm not arguing against this ideology, I'm just saying.
Enter shameless other-plug: The tags are great, because even though I don't really care much about genre in general, and even though I think something like the worst thing that could happen to this place is if the front page would be transformed into a genre selection menu... sometimes you have an idea for a remix, you have a wip and that one is a certain genre, and you need inspiration or want to compare with existing remixes, and the tags help you find them. Or maybe you forgot everything about a remix you really liked (artist, game), and then you can search for an element in it, like "female vocals", thereby narrowing your search, and find the remix. Also, browsing by genre ironically helps me find great music I would normally miss out on because I typically browse by game. Maybe I'm on the lookout for anything with a banjo in it, and so I find a final fantasty (which I never played and therefore don't care much for) remix with a banjo in it and maybe I like it and start listening to other final fantasy remixes or even the OSTs. Mission accomplished, as far as djp is concerned.
