LA and Nashville are both major music industry Cities, I think Haley would make the best of where ever she goes. One thing LA has that Nashville may not, is her 'guys'... the other S10 Idols that can be a comfort when she's not in Chi town with her peeps..., also the industry connections she's made has mainly been LA based.
I am intrigued at the possibility of Haley adding some country to her songs, she just hasn't made any reference to doing so in her upcoming songs....
(would be worse if she wants to go head to head with Taylor Swift on her turf, regarding song about 'stupid boys', which she
has said is the subject matter of her new songs

)
