Michael Jackson's Billy Jean might be the best pop song ever. Maybe not everybody's favorite, but very well could be the best. So hard to pass it up, and I don't think it gets "moldy" due to how much is in there.

Edit: If The Beatles' Here Comes the Sun falls under pop, that's probably it. Perfect melody, despite your challenge not to post it.

Ok, I'll play by the rules. Broken Bells' The Ghost Inside is infectious, but not cheap. It translates wonderfully when played live. The vocals are godly and the bass beat is a toe tapper. I've shared the live version, which is a little more upbeat and less electronic.

Enanitos Verdes - Frances Limon

Whether your speak Spanish or not, these Argentines can get you grooving along with them. You'll notice the main guitar riff, which has been shamelessly stolen and fought about by other artists, but this song predates their usage. The song is all pop, but it has bits of reggae, rock, and blues.

Latin pop and rock, the non-trashy stuff could absolutely dominate this list, by the way.

Gaz Coombes - Walk the Walk

One of the best songs from 2018 that just didn't blow up as it totally deserved to. Absolutely intoxicating from start to finish.
