I am finding that this feature, whilst much appreciated in concept, very rarely leads me to any styles that seem appropriate.

I think this is because the box is simply used to set the filters, rather than through any kind of song-matching exercise carried out by a human. This is perhaps fair enough, given there are over 21,000 songs in the list, but it means that I pretty much never use it. I also find that it sometimes sets the parameters too narrowly, so it will actually filter out some styles that might have been appropriate.

I've seen people asking on these forums for particular RealStyles to match [x] song, and the replies to these requests tend to be helpful with good approximations. I wondered if there is any kind of database keeping track of these?
