Music To Our Ears

For me, music choice plays an essential role in deciding the quality of a TV show. In that regard, How I Met Your Mother excels. Down through the seasons, the music supervisor, John Swihart, and his music department have become more successful in finding the perfect songs to infuse into the show's episodes. Even more, special music videos are designed for some characters like Robin Scherbatsky and others. They help change the pace of the show and also simply make the show more entertaining!
Clip #1: The gang finds out that Robin was originally a Canadian pop star and they simply couldn't get over it. Barney searches high and low for a music video and he's rewarded by this:

Clip #2: In Season 5, Barney begins to pursue a lovely lady who simply hates suits. That may pose a problem with Barney's life slogan, "Suit Up!" He then has a broadway moment to express his dilemma, and it's quite spectacular.

Clip #3: This is a great song that I personally like a lot from a random episode from Season 7.

Clip #4: My hands down, all-time favorite episode in How I Met Your Mother is "The Leap" season 4 finale. It encapsulates everything I adore about the show: deeper themes, Barney and Robin's relationship, and an excellent theme song for the episode. Given all of that though, DO NOT skip right to this episode, watching all of season 4 makes this episode all the more powerful and meaningful. Here's the theme song, enjoy!

In this episode Ted and Barney go through life changing events that really gives the show another boost to speed towards the ultimate goal of finding out who the heck is Ted's wife. But it's episodes like these that also make me want the show to never end. Though judging by the current season's performance, it might just be about time for this amazing TV show to finish its legendary run.
