My PC crashed not long ago. My iTunes library was wiped clean. I had all my music in my iPod, but iTunes wouldn't let me copy my iPod songs back to my computer. This was driving me crazy until I found this CopyTrans application that transfers all your music and playlists back to iTues. It saved me time because the whole thing only took 5 minutes and I didn't have to re-rip all my songs (8000). This app is the best! I just love it!!!
