Below is Amerie doing Heard Em All on Jimmy Kimmel Live, and the show she put on was average, but the sound coming overall from Amerie isn’t that catchy too put it down honestly, however, it will work for a while for some I suppose.  Again, give props to any artist making it happen like Amerie despite the lack of “catchiness” listeners like to feel in the music.  Not everyone can get there and do it, so respect.
