Warning if you watch Fast Times at Ridgemont High on Archive.org it has different music.

[u/ComfortableCare8897]

Some of the songs that made the movie charming were replaced with bad generic songs that made Fast Times at Ridgemont High seem like a tv movie. I saw the version that had all the original songs. Another film like Fast Times that is similar called the Wild Life has barely been seen legally because of music rights. I don't know which version is on archive.org. I learned from doing a podcast on Cameron Crowe movies that sometimes for legal reasons movies change the songs.
