This is SO awesome – all the background music by Ray Ellis from the first season plus some from seasons 2 and 3 of the late 60s Spider-man cartoon series. Check the tracks at 54:52 and 1:04:50 ! YouTube user 11db11 explained how he put it all together:

“I cut out every piece of music from all 3 seasons (that took like a month) – Then I grouped them together (multiple incidents of each song) – Then I built each song from the best parts of the multiple versions. – I had to EQ each individual clip to even the levels, bass, treble … – – I left the video alone so people could see where the clips came from.”
