So, have you guys tested playing back those DRM-free iTunes-songs in other devices than iPods? I read on Ars Technica forums that there are some issues with them. I tried moving one of my purchased songs ("Welcome to the Machine" by Pink Floyd) to my Nokia E61 which plays back AAC, at it couldn't play the file. The Nokia Music Manager that I used to move the file does have a setting to "Conver to mobile optimized format". If I ran the song through that, then it works.
