Yeah, if you want stuff in a particular genre, typically just ask here and we'll try to make a list for you. Although there have been so many "relaxing" and "piano" and "orchestra" and "vocal" requests that I start to wonder if it wouldn't be easier to just have a permanent list somewhere to save everybody the trouble.
Actually, the more people ask for this, the more I wonder if it might be a decent idea after all. I don't see educating "close-minded" listeners as an overly valid reason...if they want to be close-minded, they're going to find some way to do it no matter what, and it doesn't seem appropriate to force tolerance on them. Judging from the friends I have that go here, the main selection criteria people have is actually the source game and tune...should we then eliminate those identifiers as well in the hopes of inducing open-mindedness in listeners?
I guess I can understand that some ReMixes are hard to classify, but I see djp try to do it in his write-ups all the time anyway. I think a multiple tag system would help in that aspect. It might even help open people up to other genres...for example, if someone searches for "rap" and gets "Oil Ocean (WT-40 Mix)," he might become interested in ethnic, rock, or electronica music as well.
