How do I know if iTunes files are all 'lossless'?


Hey gang, bear with me as I know just enough about computers to 'be dangerous' -- my Q., I have hundreds of songs on computer in iTunes and also in my iPod Classic. I'm aware that songs bought through iTunes are MP3 only, but most of the CD's I downloaded over the years SHOULD be as 'lossless'.

How do I find out which files/songs/albums are 'lossless' vs. compressed MP3?

Thanks to any and all.

Does anyone here use any 3rd party plugins to itunes that allow native FLAC in itunes? Cheers,

Spiritualized, I hear ya, but I don't want to convert to AIFF, as my portable can only play FLAC. I want to get FLAC files from hdtracks.com and keep them FLAC, but manage only one library. Any ideas? Cheers,
