What's this song from a YouTube video? please help?!?

I saw the video about a year ago and I can't remember much, and I can't find it anywhere! it had a guy and a skateboard I think? I'm pretty sure there was graffiti in it somewhere and it was a very inspirational song and it wasn't rap it was more like pop-rock and most of the comments said that the song sounded so familiar and it did to me too. it was very colorful. can someone please tell me what song this is?!
