Farrell's new song

You're referring to Colin Farrell, the Irish actor, not the musician! Colin Farrell hasn't released a new song, as he is an actor, not a musician. He has appeared in numerous films and TV shows, including "Tigerland", "Phone Booth", "Minority Report", "In Bruges", and "Fantastic Beasts and Where to Find Them", among many others. If you're looking for information on his latest projects or upcoming releases, I'd be happy to help!
