This doesn't really seem expressive, i mean thats what music is supposed to be about, expression, but all your songs sound the same. All the guitar plays is power chords, you don't solo, drum beats are basic, synth is just cliched and the bass is weak. Your "rock star" image is soiled by the fact that you sing about "shaking it" and stuff like that belongs with artists like Chris Brown, and T-Pain. I'm also feeling a lot of unoriginality here, you guys don't want to make cool tunes, you just want hordes of screaming teenage girls... which you're getting. Not cool. Jesus disapproves of this. Try different techniques, lose the synth and add some depth to your lyrics.
