I liked Bruno Mars' early collaborations and his first album, but not what I've heard off his second album. I listen to a lot of pop, including Selena, Ke$ha, Pink, Kelly Clarkson, Taylor Swift, etc. I think having the marketing power of Disney behind you only lasts so long. Those with some talent are able to sustain their success (e.g. Justin Timberlake, Britney Spears, Miley Cyrus for a while but not lately, Christina Aguilera, Anne Hathaway) and others just can't keep it up post-Disney (Cheetah Girls, Hilary Duff, Ashley Tisdale, Vanessa Hudgens, Christina Milian).
The last ten concerts I went to are a mix of 80s (when I was a teen) and current stuff: Ellie Goulding, Pentatonix, Roxette, Concrete Blonde, Jayme Dee, Erasure, Nouvelle Vague, B-52s, Taylor Swift, Orchestral Manoeuvres in the Dark.
