iTunes Match and Songs Not Eligible for iCloud
So I signed up for iTunes Match yesterday and I'm having a big issue with many songs not eligible for iCloud. I could convert them all to AAC but what a tedious practice that would be. I have to believe there is a better way here, or something is wrong. There is no pattern to the songs that are not eligible. Some songs are older, but some are newer. For example, I downloaded a new song from a new artist that is not eligible. Any hints on why this is happening and how I can get my library back in working order? It seems like iTunes Match solved one issue and created a bigger one.
