Is anyone finding specific artists that refuse to be "Matched?" From my 20k library, a solid 10k songs were matched. But many popular artists won't recognize a song at all from my 256kbps Cd rips. Included is Billy Joel, Bruce Springsteen, DMB, John Coltrane. Further, has anyone actually successfully been able to delete songs from iCloud? I created a new itunes library and deleted the entire Match library 3 times and it refuses to take.
