I recently saw a music video for a song that I really liked but I didn't have my phone so I couldn't shazam it!

Basically it's a guy singing on the subway with everything passing by really quickly. For most of the video its just him (I think he's American but he he looks like he's of arabic descent - dark hair etc). Towards the end he appears to be travelling by taxi.
The chorus of the song is something like 'yeah yeah yeah yeah I need you by my side, yeah yeah yeah yeah I need you now´though maybe not exactly like that. He sings it in quite a high pitched voice too.
I think it's a relatively recent song but I don't think he's that well known.

Thanks if you can help!
