I would have to say right now, my favorite artist is Austin Mahone, because...
He's a less well-known pop singer; most people only have heard of him because of his one-time hits or an appearance at an awards ceremony, i.e. the Grammys, so I like that. He's also got an amazing voice--it's deep but filled with emotion and strong. Some of my favorite songs by him (though that wasn't the question...) are:
"What About Love?"
"All I Ever Need"
"Someone Like You"
"Say You're Just a Friend" (SYJAF) ft. Flo Rida
"MMM Yeah" ft. Pitbull
^^i love this kid.
