This would probably be too much of a hassle but I think it would def. be handy if there was a field for track key, maybe one that could be edited by reg. users instead of having to be posted on the forum (less work for the admins). Since I use mostly vinyl it would be nice to have an online reference instead of using my shitty ears to guess it by myself. Chemical started doing this recently but so far they only have key listings for recent stuff, and I don't know any other sites that list tracks by key (if you do, please post it!). Of course I'd be more than willing to contribute key info about the tunes in my collection, or help in any other way.
