I'm wondering what the music is at the end of S3E1, where Rick has his speech to Morty in the garage. I couldn't find this anywhere, and any of the songs that are referenced aren't the one I'm looking for. Any help?
It's incidental music from the episode, and since it's not part of the soundtrack released in October 2018 I doubt you'll be able to listen to it on its own. Perhaps it'll be included in their next soundtrack release should they ever make one.
