Country - especially classic country - waylon willie and the boys! loretta, dollie, patsy, jeannie riley
Folk music - tannahill weavers, Kingston trio, and the like
rock - aerosmith, meatloaf, ozzy, rush, u2
pop - mostly 80's stuff, pink, beyonce, saving jane
christian contemporary - life house, micheal w smith , chris tomlin, etc
Hard core rap - easy e, snoop, eminem, tupac, trick daddy, shyne, NWA, petey pablo (stuff they won't play on the radio)
Latin - alejandro sanz and shakira - in spanish thank you very much.
And of course jimmy buffett, rob zombie and weird al yankovic
Seriously, about all I won't listen to is brittnay spears type top 40/pop, most hip hop that is played on the radio and bluegrass(I just can't get into it)
