I have a situation where part of my music library is in Library->Music and part of it is in Library->Music->iTunes->Music. Everything is in iTunes when I load it up. I think the situation has arisen because I chose to organise things myself, but from time to time I use the 'Automatically Add to iTunes' folder, and then of course there are things like podcasts and iphone apps where you don't have a choice. What would be the least painful way (given that we're talking about 100gigs of music) to give it all over to iTunes at this point? Am I right in thinking that I will be stuffed if I want to use a different media player in the future?
