From way back in How I Met Your Mother Season 2, the ultimate Robin Sparkles single. It will be stuck in your head for days.

Climb on board, people. There's plenty of room on the Murder Train.

Nothing fits Barney like a suit. He sang about that on Episode 100.

Easily the most serious of all How I Met Your Mother music selection. The Mother can seriously play that ukulele.

Robin Sparkles is back! This time for the timeless track "Sandcastles in the Sand."

Marshall had the best night ever in 2009. And he and decided to sing a song about it.

Man, you just got slapped! This emotional music video is an all-timer.

Sing it, Robin Sparkles! The crooner goes grunge with the track "P.S. I Love You."

Marshall breaks out the Robot Dance in this clip from 2010. What else needs to be said?

Really, we should refer to this footage as Barney’s HOLIDAY compilation. It does include a take on The Dreidel Song, for example.

The opening notes to the How I Met Your Mother theme song never sounded so sweet.
