Sound quality, collection of music, no way to be sure. I had to return this unopened because the folks at Walmart did not take into consideration the fact that it is not packaged in a hard CD cover and they insisted on using FedEx. It is packaged in a cardboard sleeve. They put this cardboard sleeve in a giant, flat, absorbent cardboard envelope, too big to fit in a mailbox, though the CD itself, in an appropriately-sized bubble bag would have fit just fine. Then they handed this over to FedEX, who tossed it into a puddle in the pouring rain. The carrier's lie is that nobody was home, but they didn't even approach the the porch. There was someone home who witnessed the action. By the time they opened the door, the package was soaked through. Though the cardboard sleeve was wrapped in shrink wrap, there was a gap and the water had seeped in. This was unacceptably sloppy and lazy on the part of Walmart shipping and FedEx and I have a low tolerance level for liars. Don't trust either. They're useless and dishonest.
