It's all for fun, but the rules I was going by were: The song was originally written for a fictional movie/tv show/etc. The characters in said movie/tv show/etc are aware of the song, and either listen to it or perform it. It is not from a musical, which occupies a weird space where normal people break into song during their everyday lives. The song must function the way it would in the real world.
That whole thing was weirder than average, even for THAT show. When he started singing I thought it was a Black Lodge dream.
That’s the best one of all. The song barely aired and it became the biggest song of 1969, besides being recorded by a bunch of nobodies and the lead singer from The Cuff Links. Fake song, fake band, animated show, and was played in the Apollo 12 broadcast and topped Billboard for the year.
Here's a couple of favourites for me. Anything out of Walk Hard - The Dewey Cox Story, but this was a good one. Cracklin Bacon out of Super Troopers 2 was great.
This was from the movie "Velvet Goldmine," about the early '70s British Glam-Rock scene, a movie that I thoroughly enjoyed, but it seems like very person I've ever shown it to hates it. Fun fact: Director Todd Haynes wanted to make the movie about David Bowie, but Bowie would not lease him the rights to his music/ likeness/ etc. So Haynes had to have someone write all-original music that sounded like Bowie, but was not.
Serious Baader–Meinhof vibes tonight. In the last hour I've had a friend bring up the Goofy Movie out of the blue, and That Thing You Do! was playing at the grocery store.
