YouTube Musicians: Popular Songs or a Little More Rare?

I like to play songs that are just a little bit more rare. Not songs that are very rare, but not the ones that 20,000 people already made videos of. Someone told me I'd have a lot more views if I played some more popular songs. I tried it to humor them, and found that the more popular songs actually did worse because it is so hard to find them on a search since so many other videos come up ahead of mine. And I generally don't do anything to promote my own videos so that people would find them without searching.

But to me, YouTube isn't a popularity contest. I'm more excited if I get a comment from a YouTube musician that I respect than if I get 1,000 views on the video. Especially if I get an inspirational comment or constructive criticism that helps me improve.

So what type of music do you play on YouTube?
