fatboyslimfast:cse:How do i access lossless files in itunes?
If you mean to download (i.e. from the iTunes store), I don't think there are any.
To Rip your CDs in lossless, open itunes, click Edit>Preferences, choose "import settings" and choose "Apple Lossless" from the Import Using drop down menu.
AND make sure error correction is ticked.
