I couldn't find an iTunes forum so I'm posting here since I got a MacBook Retina. 1) Due to my 2005 Dell screwing up the encoding of some of my music files. (making a track in an album bounce into another track and back to original track during playback). I'm going to start from scratch and burn all my CDs onto the MacBook. My question is is there a big difference between Apple Lossless and AAC 256 bps? Previously I used the latter. I'm concerned how much more space the Lossless will take up. Also, I rememember reading on here my iPhone and iPad wouldn't recognize Lossless however there is a setting on the iPhone iPad settings that automatically convert the files to ACC during transfer. So would it be worth using Lossless on the MacBook? 2) As noted above I'm burning my albums. But I do have some music that I do not have on CDs to burn. I was thinking of getting a drive to transfer them. But it is a small amount so I was thinking of using my Dropbox account to transfer then delete them off Dropbox as I transfer them. Is that a good idea? Also, if so when I do transfer the files either via Dropbox or a drive which folder they going? Can I just transfer each artist folder from the iTunes Media folder on the PC to the same folder of that name on the Mac? Also, once I do get the files on the Mac how do I get them I'm the iTunes library?
