My altis has the original MP3 player, you
can burn and compile your favourite tracks MP3 format to ur own CD, i tried with CD-RW it works as
well, so you can have like 150 songs on the CD. The thing is that
you have gotta spend time on your computer to compile it. So you
know 150 tracks is like 10+ CDs???? and you get to have your fav
tracks.. not too bad i would say. I dunno about the quality of
sound though, have never sat in one with the CD changer though.
