Help With cd burning from mp3

i was wondering what is the best method of burning a cd?
i want it to be compatible with older cd players etc
i want to convert my mp3 files to a compatible format.?
im using nero or adobe audition.(what settings)eg.wav or???
should i use cd-rw or cd-r or does it matter?

You have to burn an Audio-CD.
Most programs can decode MP3 files while they’re burned to CD.

CD-RW is incompatible with most players (apart than more expensive and less reliable):

so using cd-r rather than cd-rw is better to play on older cd players etc…

Most players can’t read CD-RWs
