Here's The Piano Guys' latest. The YouTube description has the backstory:
Written when he was 17, "Waterfall" is like an old friend to Jon. It got him the cutest girl in his high school, made him the life of many parties, and has been a big hit with pianists and piano teachers alike. Jon says that in high school it was proof that [chicks] dig even ugly guys with skills. This tune has significant meaning to Jon and all of us at ThePianoGuys because it played a pivotal role in convincing Jon to commit to a full-time career as a pianist.
