loud feedback on some tracks listed as 0 BPM

Recently updated and analyzed library. After completion, some tracks are listed as 0 BPM. When I load these tracks, waveform is flat. Starting the track generates either a loud “feedback” type sound, or silence.
Went back to iTunes, played tracks in iTunes perfectly, so track is not damaged.

Hi Vince, 

What kind of tracks are affected? Do they have anything in common?

I did not notice the commonality earlier, as the tracks were from different genres and artists. Now that you ask, I notice that all that tracks are from a Billboard compilation CD of 80’s hits. Still don’t know why they play with no issue in iTunes. Thanks for the reply Btw.
