I like some of Bruno Mars' songs, didn't like 'Just the way you are' or 'Grenade' much but I liked the more recent singles I've heard from him. I really like the latest I've heard from him 'It will rain' as well as 'The Lazy song', and 'Count on Me'.

However, despite that I wouldn't say I'm a fan of his. But I may become a fan, who knows. It doesn't matter. I find I like a lot of songs by various artists but only those who continuously produce or at least sing great music do I become a fan of.
