This is seriously sucky. I had iTunes match until my library exceeded 25K "songs". At that point you're toast. You can't buy more capacity, you can't select what "songs" in your library you want in " Match". It's all-or-nothing. After a year - when my library crossed the iRubicon - I was done. If they're now killing your own [local] playlists and ignoring the music you have in your library - then why on earth would I even consider it?
