You know when you hear "So no one told you life was gonna be this way — your job's a joke, you're broke, your love life's DOA..." and you immediately think of Rachel, Ross, Monica, Chandler, Joey and Phoebe?
Well, plenty of TV shows have taken their theme from a legitimate song release. Here are our favourites.
Friends : I'll Be There For You - The Rembrandts
With Friends producers David Crane and Marta Kauffman, as well as The Rembrandts band members Phil Sōlem and Danny Wilde, involved in the writing process, this is possibly the most famous TV-theme-turned-pop-song. Originally 45 seconds long, the composition was later re-recorded as a full-length song about a year after the show's premiere — and seven years after the series ended, it's still played all over the world. Some people are still trying to get the timing of the "clap clap clap clap" right ...
Scrubs : Superman - Lazlo Bane
Executive producer Bill Lawrence credits star and narrator Zach Braff with nominating the song as the show's theme. Braff later directed the music video for Lazlo Bane, which features behind-the-scenes footage from the show's set.
True Blood : Bad Things - Jace Everett
Country singer-songwriter Jace Everett released "Bad Things" on his self-titled album as well as a single in 2005, but it failed to chart. After being chosen as the vampire drama's theme in 2008, the song became a hit, charting in Norway, Sweden and the UK in 2009.
How To Make It In America : I Need A Dollar - Aloe Blacc
Rapper, singer and producer Aloe Blacc lent his incredibly catchy track to the HBO series that premiered free on YouTube and iTunes last year. Both parties must be happy with the outcome, as the musician credits the show for giving him more exposure, and a second season of the dramedy is currently in production.
