This week's free single of the week at the iTunes Music Store is Tongue Tied by Farrah.

The song tells the story of an obsessive fan: "I've read every one of your interviews / I know you think your arms are fat / And you like cats and fine wines / Tongue tied / I want you / And you know I always will / Inside, so shy / If only you knew what a state I'm in".

The Music Store describes the track's "blissful harmonies, hook-laden melodies and high-octane energy."

The track is from the UK band's second album Me Too. Their debut album, Moustache is not available on the iTunes Music Store.
