It would be great if the browser in ableton had an iTunes section that referenced and showed your iTunes library and playlists. I believe serato has this. Would be nice because of all the playlists and smart playlists one could create in iTunes and not have to organize again for ableton. Could even create a unique iTunes library that just had files and playlists for your live set.
Maybe this is already possibly and I'm missing something, but I don't think so.
