song title from video description
 

It's been driving me insane. The video is maybe 5 years old. I don't think the band appears in the video at all, the video is of couples making hearts with their hands and holding up signs, singing along to the song (I think they had on headphones?). There were old couples and young couples, some were on the streets, some were sitting on a couch. The singer was male, and that's all I remember- other than I liked the song. Ring any bells?
