This song has been stuck in my head for a week now and I really want to find it! https://www.youtube.com/watch?v=O3IcQUT5aMQ In this video a guy is playing a song starting at 3:56. You can hear it pretty clear at 4:13 but my french is absolutely terrible so if anyone could either make some lyrics out or even identify it I would be beyond grateful!

Hello,

The singer is belgian, his name is Loïc Nottet, the title of the song is "Rythm Inside".
