@jontalk -
A while back I bought a DRM removal tool called Aimersoft. It took me forever to get about 200+ songs changed to .mp3s
I then used Kies to sync my iTunes library to my SGSIII, and all the track play, as it should
Anyway, after all that, last night, a friend on Twitter said, and I quote, "Just use Google Music...". I protested that it didn't support .mp4 tracks. After a bit of testing last night, it DOES. All you need to do is install Google Music, set it to upload either all of your iTunes library, or just the playlist of choice, and ALL the music plays, period.
I've tested it. Albeit, going forward I will only buy music from Amazon. After all, if I buy it, it should be mine, to do with it as I please (same thing Bruce Willis has said only this week).
Before I left this morning, I set Google Music (Music Manager) to upload all 800+ songs to Google Music. I need to do the same for my missus, she has 3000+ songs. Yeah, fun times...
