I've been known to drain my car's batteries by opening the doors and my hatchback and blasting my radio so I can listen and ride. I won't notice exactly when the music stops, but all of a sudden I think...."Ahhh dang it." I'll have to get a jump start. xP
But I stopped doing this when my car died and no one was at the stables and it was night....I had to call a friend to drive out and give me a jump. From then on, I use head phones and my Ipod. If I'm on trail I'll only have one in, in the arena I plug both in and I can't hear anything....I love it.
Still trying to find a good, loud portable radio I can use and plug in without draining my car...or spending $500 --->That money is going to a new saddle before a radio.
EDIT : I forgot half the question D= I listen to almost everything, Rap, county, Show Tunes, Rock....Pop...you name it, I'll listen to it.
