Rachel Platten is a new artist making the rounds with her first hit, "Fight Song." And with 9 million views on this video already, I think she'll probably do OK for herself.

The 34-year-old singer got a huge boost from Taylor Swift, who recently brought Platten onstage with her for a duet of "Fight Song."

If that's not a guarantee that your song is a hit, then I don't know what is.
