I don't know what people are thinking saying that 256kbps AAC sounds better than 320kbps MP3. Too me it 256kbps AAC sounds tiny, flat and even has a metallic type sound to it. Since I used Apple Music straight for a month then went back to Play Music I could not believe how much more natural and better sounding Play Music sounds. It has more depth and punchy base as AM sounds much flatter and lower. Now I no auto file by any means and I don't use $500 headphones but I do notice. Since many iPhone users using AM use those horrible cheap white earbuds that come with iDevices is why many can't tell the difference. Now if AM were to offer 320kbps AAC or lossless audio then we can talk.
