I love it. The more mainstream the better. Screw originality. If it's on the Billboard Top 100 Chart, there's a good chance that I'll like it. Biebs? Bring it on. Pink? Yep. I love being able to sing along. Better yet, I love when there is a story that speaks to me. Maybe it's simply that I like pop and folk music and that they just happen to be pretty mainstream. But they are mainstream - liked by most people - for a reason. It's because they are good. With that, think it's time to put some mainstream music on and get to bed.
