I really like this song I heard it on the episode and I was like damn that’s catchy the last time that came out from Lisa was from the Simpsons album from 1990, “god bless this child” the whole album is great fun
Jokes aside this definitely sounds like a Smiths song, just change the lyrics a bit Everybody is horrid deep down inside, accept you! Everybody is horrid and dear I fear I do to!
