I'm sure everybody dislakes the music in GT5, so I would like some cool songs I could listen while racing;)
Here are some songs that I like very much so you could make an idea of what
to suggest
Petey Pablo - Show me the money;
Finger Eleven - Paralyzer;
Madcon- Beggin.

How about Dirtyloud - School Of Funk?

Get the music from GT3 and GT4. The music was much better and great for racing.
