I stumbled across Uplaya.com. It's a website that alleges it can detect if your music has the magical elements that have also been present in past hit songs. Figured it was a joke, which it is, but tried it for fun anyways. It rates your songs on a 1-10 scale. You can do 2 for free.
I started with one of my own tracks I'm working on, this one to be exact..
It got a whopping... 4.7
So then I decided to have some fun with my second free upload. I put up Daft Punk's Harder, Better, Faster, Stronger. They won a grammy for it, so I figured it would be considered a "hit".
The score for Daft Punk's song? A chart shattering 6.0 (keep in mind were going for a 9+ here).
If you're a real sucker you can pay $90, and they'll do the Magic 8 Ball on 15 of your tracks.
