What artists do you think should have been big in the US?
Pixie Lott should have, but she released one unpromoted single as well as her GH album here (which also had no promo here). Her label mistreated her career. She's only 24 so she has plenty of time.
Alexandra Stan and Inna also should have been smashing during the dance pop and EDM eras. They could get cute radio hits with the music they're doing now, but I don't think they even want to be big in the US.
Nicole Scherzinger was done wrong in general, although I guess it's kinda her fault for ditching her backup dancers.
she's had moderate success here, for sure, but she should be huge. her music is obviously more alternative than mainstream pop, but it's still accessible enough for the GP to enjoy. oh well
She still has a chance, though.
