When for whatever reason, the artist of a song decides to throw in some weird experimental trash that just doesn't fit into an otherwise great song, often leading to being unable to enjoy the song as a whole.
*Listening to the radio*
Joey: Ah man, this song is great! Can't believe I haven't heard it before.
Mark: This part is good, but there's a bullshit sequence coming up.
Joey: What? *Weird experimental sequence fades in* Noooo! Why?!
