It really depends on my mood.
I've got over 2200 songs on my usb that's plugged into my deck.
Everything from classical, to waltz's, to big band, rock (50's right thru to the 00's), disco, funk, pop country, pop, motown, r&b, blues, jazz, a few punk, a couple of grunge tunes, instrumental and acapella tunes, some dance tunes, hip hop, tv show and movie themes, Boston Pops Orchestra and London Philharmonc.
Everything from lullaby's to head banging music. I've pretty much got it all. And believe me, I do get some strange looks sometimes when I have the top down and my tunes are blaring.
