Can't say I'm surprised they had to break the crowbar out, and even then, that cassette's probably salvagable even WITHOUT having to put the tape in a different shell...
For about 25 years of using the things, I think I've only ever damaged ONE to the point of unusability (can't even remember wtf happened to it, but it was severe) and maybe 2-3 more enough that remedial measures were needed to keep them going. If you can avoid the triplet horrors of tangling, dampness and fungal rot, they're pretty much indestructible.
Missed opportunity to give us the recorded-to-tape-and-back-to-digital version of the theme tune though. Or maybe just a fair-use snippet of something off that album before you "finally" "killed" it.
(mail it to me - I'll revive it!)
