TIA If you want to burn them on to a CD to play in a regular CD player then I think you need to put them all in a single playlist and from the File menu choose "Burn Playlist to Disk". Before doing so ensure that iTunes > Preferemces > Advanced > Burning > Disk Format is set to "Audio CD". I assume that by "the store" you're referring to The iTunes Store (tm). For the purposes of clarity, could I ask you to refer to that as "the iTunes store", rather than just "the store". I went to the store & bought a CD; I went to the store & bought bread; I've run out of cigarettes so I'd better run to the store before it closes. A regular CD which you buy in the store (a regular CD which you buy in the supermarket) does not contain .aiff files. If you buy a copy of "Confessions on a Dance Floor" on physical CD from an actual store and put it in your Mac and the tracks appear to be .aiff files then this is actually the operating system abstracting the contents for you - if you drag & drop the .aiff file onto your desktop then the track is "ripped" to .aiff on the fly. A CD actually contains a single digital stream of bits in a spiral from hub to rim; were you to save a bunch of .aiff files onto a CD-R then that CD-R would contain a filesystem as well as those files, rendering it unreadable on a home CD player. Stroller.
