I have experienced this with NWA's "Gangsta Gangsta". Another delightful thing is that the volume is system volume * speaker volume, so that if you turned up the system volume because you were, e.g., using a quiet pair of headphones, this is now blairing at a total unreasonable volume, perhaps even destroying your car's speakers.

This can include that porn you were watching in your mobile browser the night before. Ya know, theoretically.
