Country music.

I must admit I used to hate country music and thought it sentimental crap and rather embarassing. Well it can be cheesy, but it's very infectious and the more you listen and get into it, the more you like it. It may just be a question of age!
It's particularly good driving music. Maybe it wouldn't have quite the same appeal if you were stuck in a traffic jam on the M25, but round here it seems just right.
Even if you can't stand the stuff, you have to recognise it is a living, evolving, much loved music tradition. The people can sing well and they can all play an instrument, quite often, half a dozen. You will often get family groups, where they have been playing and singing together since they could stand up. It has a huge following and the centre of it all is Nashville. There is a television channel devoted entirely to country music and we quite often listen in for a while. The concerts all sell out and if you watch the audience, they all know the words to all the songs.
The songs are sentimental, patriotic and religious. Pretty straight forward stuff and the words are important. They are about life, love, God, patriotism, kids, having a job, drinking beer, cars, being ordinary, your mum and dad and the like. The words can be very funny and quite clever.
I'd never heard of any of the artists before, except a few who cross over into the mainstream. The men, for the most part, are not things of beauty. They tend to have deep voices and southern accents. They mostly dress like cowboys, jeans, open shirts, cowboy boots and hats and look very different from your regular singing star. The women are it seems usually blonde, pretty and have southern accents. Difficult to describe the way they dress. Shall we say tasteful is not what springs to mind.

I think music traditions are to be cherished, and this one is alive and well and very american.

Try a few of these:

Billy Currington 'Pretty good at drinkin' beer' and 'People are Crazy'
Easton Corbin 'A little more country than that'
Craig Campbell 'Family man'
Chris Young 'I hear voices all the time'
Brad Paisley 'This is Country Music'
Jason Aldean 'She's country'
Blake Skelton 'Old Red' and 'Honky Tonk Man'.
Dierks Bentley 'Rovin' gambler

See if they do anything for you. They might make you laugh, if nothing else!
