Yeah, it's kinda deliberate, so not really a bug, rather a limitation. The detection algorithm uses combined waveforms. In my SID core - since most if not all original SID cards were using a 8580 - I simply emulate the combined waveforms of the 8580 all the time and not that of the 6581 (which is kind of silence anayway) since it makes the code much simpler. The 6581 only differs in the filter cutoff frequencies and the DC levels.
There is no C8M tool other than a Perl script by TLC that I can share maybe but don't expect miracles  Preparing .SID files is no joyride either. There is no universal solution, so no tool. Writing a generic music detection algorithm is not an easy task I think.
