Thanks for your suggestions, everyone. I was not aware of the filesharing option on iTunes (I'm totally new to mac products, and have always avoided iTunes as much as possible in the past - still figuring all this out. And, to be honest, I find Apple's various help sites really counterintuitive - I seem to dig forever before I find the answers I'm looking for). Now my problem is finding a decent flac-playing app that will allow me to create playlists with a number of different file formats in it. I teach music at a university, so I'm constantly bringing in recordings to my classes - but I've got them in a number of different formats, and it's just an extra step if I have to convert everything to one format before every lecture, rather than simply having my recordings all handy in one place and being able to draw from them when I need them. Can do that with the external hard drive I have now in conjunction with the computer in the classroom, but it would be so much smoother if I could do it all from my iPad. Any suggestions?
