Just wanted to let everyone know:

TuneUp Media has been scurrying to assemble an awesome new app to help you manage your music collection, which just came out in Beta. I had the pleasure of meeting the CEO and talking to him about it - and I am really impressed.

It 'cleans' mislabeled songs by digitally listening to the song, and (powered by Gracenote) fixes the info (ID3 tags) with the correct details. They also have some very cool album art fixers, and a list of concerts from artists in your collection that are coming to your area, as well as some other music discovery options. I downloaded it and think its great!

Check it out for free, and let me know what you think!
