I've been listening to Edith Piaf lately. I love how expressive she is as a singer. You don't have to know French to understand what she's saying. It's that kind of music that goes straight to your soul.
Her music is also super old, and I had no idea who she was until last year. I've never heard anyone I know talk about her.
I also really really love Motown and golden oldies. I just love that era of history and time, and I think the music just has so much personality to it. My favourite thing use to be to drive home at 11p on Sunday nights after work (Sundays are Golden Oldies night on the oldies station) and just sing along to the songs.
What unusual music do you like?
