Bands and solo peformers doing 180's with intent other than musical improvment(diffrent genre or not)is a display of lack of integrity...
Wanting to appeal to an audience other than the one that loves the music you make and you love as well has a trail of money or other incentives right behind it.
Its a compromise not only personally,but musically too.
If you want to do something different,then do it well and to full effect.
It has nothing to do with a change of heart/mind...its a change of 'drive'...
Later! \m/
Try once,fail twice...
