I took a look. Just a few comments:

Typo here, I think you meant "you're": "Formats lyrics on your screen to be easy to read while your playing an instrument."

It took me a little while to figure out how to create an account. You should probably let people create their own account on your site. It seems redundant but I think it's an accepted convention.

I clicked on "try it" and I can't honestly figure out how to do anything. I clicked all over, tried dragging the red bars, tried editing text, etc.

Hope that's helpful, and best of luck.
