How to delete everything in my iCloud/iTunes Match
Is there a way to delete all the music that I uploaded via iTunes match? I messed up my library by adding my laptop, and I want my desktop to serve as the hub/single source of music. Now I have a lot of errors (due to files being on both computers) saying that I have duplicate copies of songs. Can I just delete my iTunes match and start over?
