Dinosaur Jr - Blah, from Melrose Place: The Music [1995]

Yep, Dinosaur did appear on this soundtrack, and it's a song that you can't find on any other release. It's a pretty decent song, a must-have for any completist, worth a listen at 320kbps, and definitely worth picking up the CD for (used on Amazon would be my preference).
Enjoy. *This is only the Dinosaur song, NOT the complete soundtrack
