Yes, you can burn a CD from any iTunes playlist. When you have created your playlist (about 20 tunes), put a blank CD into the cd/dvd drive then go to the file menu and click burn playlist to disc you will be presented with a dialogue box where you can choose the type of copy you want e.g. Audio or MP3, whether you want any gaps between the tracks , quality of recording etc.. When you have made your choices, click OK and Bob's your uncle off it goes. If you have too many tracks in your playlist iTunes will tell you and ask if you want to record on multiple discs.
If you have a CD player which can play MP3 tracks you can fit many more tracks onto an MP3 disc.
