altered music on episodes- Street Wise!

I can't believe they changed the music on this the last episode. "Street Life" was the perfect song for the episode and they replaced it with some generic song on the TV Land version. What is the point? That's my question. I had most of the eps on tape from a local station and original eps from NBC beginning in 1989. Foolishly I taped over (before I was able to afford a bunch of new blank tapes) most of them when I found a new show to obsess over (I kept Street Wise and a few others). I'm glad I have the end of Hunter and McCall in it's original form. Baffles my mind why they would tamper with the eps.PS, they are bleeping out words also. PAX did that when they aired Scarecrow and Mrs. King.
