Hi, My library just got messed up. Badly. I opened iTunes today, bam, it was all blank. No worries. I deleted iTunes Library.xml and managed to select my library from iTunes.tmp. Unfortunately, it happened again so I lost it all. I am trying to import the folder "iTunes Music". I have around 500 songs. However only 400-ish import. I've noticed all the ones that import are MP3. Why don't my M4As import? I have recently moved to ripping discs to M4A, as they provide a better quality than MP3 at the same bitrate. Even if I go to Add File in iTunes they do not add. I've tried creating a new library, reinstalling iTunes no luck. Any ideas? These m4as are ripped from CDs so they should be DRM free? Thanks a lot!
