Rockstar has posted some interesting backstory about the songs used in the Gay Tony debut trailer and the "Meet Tony Prince" clip:
"Episodes from Liberty City is designed to be non-stop, over-the-top action from the instant you begin playing, so the track 'Pjanoo,' a piece of euphoric piano-led house music by top producer, Eric Prydz, was the perfect track for the debut trailer. 'Pjanoo' was a summer club anthem in 2008, reaching number two on the UK charts and epitomizes the vibe of Tony Prince’s signature club, Maisonette 9, in The Ballad of Gay Tony."
