I have tween/teenage daughters. I can tell you unequivocally that the music that they and their friends listen to (radio) is NOT guitar-based. They are all mainly into Lady Gaga, Katy Perry, Kei$ha, Bruno Mars, etc etc... Any guitar-based songs on the radio will generally get a quick "Change the Station, Dad !!" Now, whenever I hear a Lady Gaga song on the car radio, I generally hear this in order of prominence in the mix: 1. lead vocal 2. backing vocals 3. fuzzy, sawtooth synths 4. clean synths 5. synth bass 6. drums Now what if you replaced #3 with distorted guitar parts, and #4 with clean guitar parts? In other words, you kept the vocals and rythm section the same, but you replaced the synths with somewhat equivalent guitars. Would it still hold the same amount of appeal to teenage girls? Or would they run away because of those dreaded guitars?
