Thanks, OP, for starting this discussion. It has helped me better understand what Tune-Up does and does not do. 
Always look at reviews before buying something.
Yes, not sure why people would buy it, but live and learn...
For example:

She.btw...lmao at the guy that re-imported 400CDs
I agree, but its hard work and consumes SO much time.Each to their own I suppose. I actively enjoy doing it manually, filing it in the relevant playists and rating it. I find it a great way to unwind after a hard day. It's cathartic.
