Replace Previously Purchased iTunes Music
I have many tracks that I've purchased from the first generation of iTunes that I would love to replace with today's current higher bit rated music that are non DRM'd. Many tracks are DRM locked with a bitrate of 128 Kbps. Does anyone know, if iTunes allow users to upgrade their tracks to the current non DRM with higher bit rates? I've already upgraded my personal music to ALAC, now I like my purchased tracks to be better than 128 kbps.
