I think partly because I want to be them. Slash imitate all of their songs.
Check this badass out. Her voice is SO unique. She's from Belgium, and has the coolest voice, is only 19, rhymes like a damn Jamaican, and is beautiful.
Listen to her kill 'Aint No Sunshine' HERE
And Eliza Doolittle, I do love your voice so much. Her album's not really my style, but this cover of Cee-Lo is definitely on point.
