I'm moving into my own place (again) in the next few weeks. Before I go, I'd like to rip some of my roommate's CDs to iTunes. But, since it seems digital audio formats keep changing, I was thinking it would be best to rip songs in Lossless, and then convert them to AAC (or whatever format) in the future. Is it possible to encode some CD's in Lossless, and put them in an external folder? And then is there an easy way to use iTunes to convert the Lossless files to AAC for my internal hard drive??? Or am I just making way too much work for myself???
