- "Listening to quiet music can seriously damage your credibility!"
- — It's Unleashed FM
As the rest of the radios of GTA, the idea was to showcase a particular style of music, in this case heavy metal/hard rock, with fictional band Stikki Fingers' "4 Letter Love" being produced in the style of AC/DC and hard rock bands.
Brian Baglow was responsible of writting the lyrics of some of the songs in the game, including those from "4 Letter Love", which have crude profanity ("So beat me, bite me/ Now whip me, fuck me/ Come on, wank me/ Now go down and suck me"). In the words of Baglow "It was an 18-certificate game so we could get away with a fair amount. It was unique, there’s not so many jobs where you can go into your work, come home and go «Well today I wrote the lyrics for a really, really incredibly blasphemous, sacrilegious and generally filthy heavy metal song»".
