What are some songs with good harmony?

I like pretty much all kinds of music, especially pop and rock. For a
better example, popular songs with harmony I listen to include:
"Africa" by Toto
"Dreams" by the Cranberries (also "Just My Imagination")
"Everywhere I Go" by Lissie
"Oviedo" by Blind Pilot

And also a lot of 50's-70's music where the artist included a group of
singers...

Anyway, I'd like to find more songs with beautiful and evident
harmony. Thank you if you can help!
