Is there a way to convert all my tracks in iTunes to 128Kbps without having the original tracks imported into iTunes aswell. I'm picking up a 128GB SSD (going from 640GB HDD) and wanted to put a majority of the compressed/converted tracks onto the library on the drive itself. (similar to how I do it with my iPad). Is there a way to drag and drop the tracks into iTunes and auto-convert them on the fly without having a huge lossless file and the 128kbps file? thanks!
