Locks Up

Just bought a new MacBook Pro. After transfer all my tunes over, my 6000+ songs ended up being over 105,000 songs. Talking about a lot of duplicates. Anyways, downloaded this app, and all it does is lock-up. Their support says that it’s due to the number of songs. They will not refund my money.

RIP-OFF APP.! WASTE OF MONEY! If you have a large library, DO NOT PURCHASE!!!
