I use CD-RW for MP3 with my Car Audio System. You need to check do
your Car Player Support VBR MP3 Encoding (Mine Support). Most of my Song
are encoded with VBR-320k for better sound with only a bit larger file size compare
with 160kbps MP3. Try check your problem songs at WinAmp to see if they are
VBR or not, check also song have no problem if any are VBR. If some no problem
song are VBR. Then your car player support VBR MP3. So is the Disc problem.
I use CDRW for Car Audio like Cass. & MD. I keep re-write when there are new songs.
No problem so far. The weather I live "In Car" can high like +50C to -30C. Even So,
my Cheap CDRW never skip & can stand for this kind of Temperature!
Also, 1-2 pcs of my CDRW are re-write more than 100 times & still Rock!
