It was performed by Dirty Loops for Samsung Galaxy S7 and S7 Edge. But most viewers (from other videos) said that this music was the worst and some of them it sounds similar to the musics from Wii Sports and Mario Kart (I do accept it <img src="{SMILIES_PATH}/icon_e_smile.gif" alt=":)" title="Smile">).
Why they hate it, it has a more bouncy and uplifting melody (this melody could fit for a racing game). I like this one and the S2 and S3 version.
