Outro music is I Wanna Dance With Somebody (Who Loves Me), by Whitney Houston, because this song is inevitable.

Great lessons to learn from one of the all-time road songs, a cover that understands the assignment more than the song — oh, and Rich flubs his kids' birthdays, but that's OK, because we only recorded this on Father's Day. Life Is A Highway, originally by Tom Cochrane, covered by Rascal Flatts.

Outro music is Another One Rides The Bus by Weird Al Yankovic.

A classic that somehow remains a secret, and a listener leads us to a great musical discovery. The Ghost In You originally by The Psychedelic Furs, covered by Robyn Hitchcock.

An impossibly compelling songs from one of the most important writers and performers in American music, and a great band tries something different. Dancing Barefoot, originally by the Patti Smith Group, covered by U2.

Absolute pop genius from a song that wasn't supposed to be pop at all, and a cover that's a terrible fit which helps to make it even more awesome. Call Me Maybe, originally by Carly Rae Jepsen, covered by Leo Moraccioli.

Outro music is We Are Young, by Fun, just to remind you that the bar was high in 2012.

The song that brought K-Pop to the rest of the world in spectacular fashion, and a cover that's totally not punk, but really is underneath it all. Gangnam Style, originally by Psy, covered by The Cleverlys.

A powerful, insightful, and moving song from someone who, on the surface, is the unlikeliest source, and two covers that drive the point home in an unbelievably compelling way. Only Women Bleed, originally by Ailce Cooper, covered by Etta James, and by Ike Turner featuring Tina Turner.

Outro music is Welcome To My Nightmare, also by Alice Coper.
