Hi artgriff: What I would do is high lite all 7 tracks
and using the “SPLIT TOOL” from the tool bar—it looks like
a pair of scissors ---- is place a cut on all 7 tracks
right after the music ends and a 2nd cut right before
the music starts again. Then using the mute tool
or eraser tool, mute or silence the talking — your choice. 
remember to high lite all your tracks

PS: It should be easy to spot the Music vs. the Talking by
looking at the waveform. The music should be a bigger wave form
and the talking much smaller. And remember you do have UNDO
in the edit window if you make a mistake.
