What are some songs that have a lot of vocal harmonies, a lot of different instruments, or both.?

I recently bought new audiophile headphones that sound amazing. Yet, I want songs that just sound amazing. I like the way handlebars by flo-bots sounds, adam rafferty superstition, fireflies by ocean city, john butler: ocean, and the harmonies of people like Lauryn hill and even The dream. I have had a hard time finding more artists that utilize harmonies a lot. Also, I want more songs that have many different instruments. I like all types of music including clical, hip hop, and rock. Overall, I just want any song that will sound amazing on my new headphones.
