A song where the song usually has one good line. People have this song in their playlist for clout when other people/friends look at their playlist. Spotify premium users usually have this because they can just skip the song after the line.
“Oh yeah, I love *Spotify song*, I know the song by heart”
“Wait, can you sing me some lines in the song I forgot how it goes?”
“*sings popular line*”
“What else, I still don’t remember”
“Jeez, I forgot it the words, this never happens”
