A few of my favorites were: OK Go - I Won't Let You Down. Simply incredible choreography. Although the song isn't my #1 favorite, it's pretty good, but the outstanding choreography really makes the video. The Weeknd - In The Night. Oustandingly done video in my opinion, along with The Weeknd's other videos. This one's my favorite though. Good song with a cool video to back it up. I would recommend age 16+ for this video though, due to some gore and violence. Adele - Hello. She is such a talented singer and a great human being. The song is very overplayed, but there's a reason for that - her talent is incredible. I know for sure I saw some other really good ones, these were just a few that came to mind.
I agree, hello was good. Another video I was quite fond of was by paramore. Gah! Keep finding videos to post! Lol
Dangerous - Big Data feat. Joywave Not gonna post the link because it's kind of twisted but it's still pretty hysterical
I couldn't find a good video for it, but feel free to search for any recording of P. I. Tchaikovsky's Ouverture 1812 that includes cannons at the end.
Favorite Paramore song too: I need to stop listening to music through youtube or I'll keep finding these! XD
