For me usually I’ll get hung up on a certain lyric that makes me think, then I start to hear the melody, then I feel the urge to listen to that song a lot. This happened to me recently with “If I Believe You” by the 1975. The lyric was,
"And I had a revelation
I’ll be your child if you insist
I mean if it was you that made my body you probably shouldn’t have made me atheist."
I love that line and honestly I haven’t stopped listening to that song. It’s truly a piece of art, I reccomend it. Similar experiences with songs include my favorite song of all time “Waiting For The End,” “21 Questions” by Waterparks, “Who Do You Love” by Marianas Trench (My other favorite song of all time. It’s a tie, really.), and “Cancer” by My Chemical Romance.
