Tuneup to clean itunes

Hey guys, I recently downloaded the trial version of Tuneup to see if I could clean up my iTunes Library. Needless to say, I couldn't figure it out. Has anyone used this, or a similar application to organize iTunes?

I like CoverScout and SongGenie

Thanks, and sorry it took me so long to reply. I downloaded the demo version of SongGenie yesterday, and I must say it is very smooth and was able to determine the correct information on some pretty obscure songs. One question I have though, is there a function within it to get rid of duplicate songs automatically? I searched around the website and played with the options a bit, but didn't see anything. Even if not, it's still alot easier to use than Tuneup, so I'll probably pick up the full copy next Friday (payday). Thanks again.
