I wonder if it's something you could crowdsource -- if you have a list of your collection, you could just put the titles in a doc or something and let people have at it.
[EDIT] BTW I just started playing with the EQ. WOW that is a fantastic feature. Such a simple thing and I love being able to turn up the low range/high range as I like. Another level, because almost always I want more bass.
[EDIT2] Granted I don't go to music sites that much on the internet, this is happiest I've been with a site like this since Madeon's Adventure Machine[0].
You can instead turn ethe other frequencies down and then your volume up, same effect ;)
Out of curiosity, was this before or after the Epic acquisition?
