The only other racing sountrack that I remember well was the first Gran Turismo, but that's only because even back then I was a fan of Ash and they were all over the soundtrack.
Also, another cool feature in MSR that's never been done elsewhere, real time day/night cycles. It worked off the DC's internal clock to determine if the tracks you were driving in would be in day/night e.g. playing it at 12:00GMT would mean the tracks in London would be in daylight, but driving in Tokyo would be 8:00PM, making the tracks drive at night. Some thought of it as gimmicky and I guess I could see that, but again, I felt it gave each location some atmosphere.
