You have one song

Rush: Spirit of Radio

Chemical Brothers (and by extension, electronic music in general):

One Too Many Mornings

Future Bible Heroes - I’m a Vampire (since apparently nobody’s posted Losing Your Affection to YouTube).

Huun Huur Tu - Tuvan Throat Singers

The song is Ezir-Kara

A great suggestion for a great duo, and it’s really hard to narrow down to just one song, but to be contrary I’d probably choose I Don’t Know What I Can Save You From (apologies for the Lost video, the only album version of the song I could readily find on YouTube.)

Keeping in the S/S vein, I’d hope that Die Alone could win people over to Ingrid Michaelson as more than “that chick that sang in an Old Navy commercial” (The Way I Am).

Arcade Fire - No Cars Go. One of those rare songs that I actually had to stop what I was doing upon hearing it, just to learn who it was. Then I listened to it three more times.
