UnCrate reviewed Tune Up and here is what they had to say:
When we reviewed TuneUp, we said it was “quite possibly the most important piece of software any music lover can buy.” And with a beautiful new facelift, TuneUp is still a must-have organizational tool that automagically cleans up your digital music collection. TuneUp plugs into iTunes to fix mislabeled music (like “Track01”, “Unknown Artist” and “Jay-Z” spelled 5 different ways), fill in missing cover art, alert you to concerts and other cool stuff.

Here is a demo video for you to enjoy.
