I came by this on Twitter. Great stuff, if you're anything like me having a hard time finding the right tags.
They are also offering to do it for you for a fee, might be worth it for some, still great free info in the weblog.

Something for everybody.

Thanks for sharing. Tagging is indeed an involved process. Interesting business they've got, but for big companies I could see how it could be useful to have that human element.
I've been keeping a spread sheet with my tags and descriptions for each song so once I've done it, I can at least copy and paste as needed.
