I'd seen this with the old (2007) build of RoadRunner I had installed and it was new from the much older (2005?) build I had before that. RideRunner still has the bug. This just one example of a music filename that gets mishandled - there may be others due to different symbols characters.
The filename is 'Am I the Only One (Who's Ever Felt This Way-)'
RR shows just ')' in the music list.
