TuneUP is an an application designed to help keep your iTunes library more organized. While a library of only iTunes Store music will be tidy indeed, if you have acquired music from many different sources, the ID3 tags might be a bit confusing.

TuneUP works by comparing the unique sound print of each song to a database, and if new information is available, TuneUP will fix the metadata and rename your songs. It's sort of like having a genius put your books on your shelf for you. Not only does it help with naming, but the software also is able to download album art automatically with a few clicks.

While the design of this software is superb and visually appealing, it doesn't quite deliver in the area of organization. It does indeed make more coherent ID3 tags for songs, but we had hoped that it would properly shelve everything into one album each, rather than the usual album fragments, (with track 1 and 4 in one album, 2 and 8 in another, etc). Hopefully this will be refined in the final release.

TuneUP is in private beta, but we've got 100 invites to give away. Just click the link after the jump.
