So, blinktwice4y is one of the many youtube artists I subscribe too. I have only recently started listening to him more though, and I think he is absolutely awesome. The man behind blinktwice4y is Sam Hart, and he both covers and writes his own songs. His songs are very witty, well written, and usually pretty funny. He is most known for his song Mario Kart Love Song, in which he uses the awesomeness of mario kart to make a really cool love song:
He also took part in a recent collaboration (kollaboration) on the kollaboration00 channel. I would highly suggest checking that out too, it is filled with videos of insanely talented people. In addition to his mario kart love song video, I would suggest his song As You, sung with Esna Noon, who is also ridiculously talented! See below for some links!
