Real issues, like recognizable music in the background, or bogus issues like some cryptically named company claiming visual and audio rights to everything?

In some cases there is background music.  I've switched to Steinberg's SpectraLayers Pro.  Just tried it on a segment of the audio for Cal at Stanford. As far as I can tell, it removed the music without doing too much damage to the vocals. Uploading that right now.  Stay tuned.

There are other cases where I can't hear any music (even with my hearing aids).  Still trying to figure those out.
