In the NJ1015 Studio

There are some things you can't unsee, and some things you can't unhear. We're putting the NJ 101.5 Low-Rehearsal Band's latest masterpiece, "If I Had a Billion Dollars" into the latter category.

Jax — who finished in third place in this year's season 14 of American Idol — has been one of our favorite guests throughout the year. But in February, we learned she's got REAL talent.
