Same! I love to sing in the car when I'm driving alone. Some of my favorite songs to sing along to are:

Anna Sun - by Walk the Moon
Pompeii - by Bastille
Mr Brightside - by The Killers
When You Were Young - by The Killers

I haven't ever taken singing classes, so I don't even know if I have the voice for this kind of thing or if I'm doing things right. I honestly don't even care all that much, as it's not like I plan on going on anything like American Idol or whatever.

It might be fun to have a PXR karaoke, regardless of how bad we do. XD
