I recently copied all my music on to external hard drives. To save space I want to convert the files to a format that doesn't compress the music, so I won't use MP3 as the format. I can convert to FLAC or Apple's MP4. Either will net me about 50% of the original size. My issue with flac, I can play the files in Windows' Media Player, but only one track at a time. MP4 works in both iTunes and Media Player. Plus, I can queue up more than one track at a time.
Are there any formats that any of you are using that don't diminish the sound like MP3? I have 24 TBs nearly filled and I need to make room still so I don't want to leave the files as WAV.
