tape screech

Hmmm don't fancy getting WD40 inside the deck. Might try the heat technique as described at http://www.ehow.com/how_6618905_fix-squeaky-audio-cassette-tapes.html. I do have a reasonable rip, already uploaded, which is probably as good as is possible with the current condition of the tape, so it won't be a complete disaster if the tape treatments don't work. 

BTW it's a BASF LH super 120, so probably a function of the formulation, the thin-ness and storage is at fault.

And at least the screechy tape doesn't seem to have had any ill effects on the heads.

Same thing with an old commercial tape of the Damned's Black album ; never had it on a DIY/blank cassette though ! Tried everything - loosening the tape, re-housing, dif players.The problem must be in the tape material itself. Aadam is right though, sometimes noise is caused by restricted tape movement.

You have a day or two to get the sound off the tape before it blows up! (well not quite, but the tape soon reverts to screeching and will be in a worse condition...)
