I'm a huge fan of Jess Greenburg! She is a YouTube singer and plays acoustic guitar
I've never heard of her. What kind of music is she belting out? I'm a punk and metal fan. 
She is a huge fan of AC/DC, Guns N' Roses, and Red Hot Chili Peppers
I wonder if she really is or just a poser to look cool.
Well, she posted a cover of AC/DC's "Highway to Hell" in 2013, which brought her a lot of attention
I wonder if she has longevity and sticking power? I've never seen her on you tube. Is she old?
She is in her early 20s, she began posting cover songs on Youtube in 2010 at the age of 15
I'm doubtful. I can post cover songs and I can't sing. Do you like her sound?
