any 1 who can hlp me out here i just bought a sony stereo but i cnat play mo3 files on it any1 know what to do (exept buy the cd´s)

A lot of typos and the problem is not very clear to me.
Are you trying to play MP3 files on your stereo, or are you trying to play Audio CDs which are made by burning MP3 files as an audio CD?

Perhaps this topic helps (deals with a similar problem):

many sony dvd stereo’s can’t read cd r 's because they don’t have two lasers built in

but almost all sony standalone CD-players can read both CD-R’s and CD-RW’s :cool:
