Hi, iI have the same problem as you I can't decide between rock or blues. I grew up listening rock music. But the feeling I get when playing the blues is the reason why i cannot choose.

At the moment I am going back an forth between the two styles. But i get the feeling that this method is holding me back because i cannot commit to one style and therefore I get the feeling that i am wasting my time. And have to start over again after switching.

I finished fundamentals months ago and I have still not decided. All the music I listen to is Rock based. But Blues is so relaxing to play.

And i know the best thing to do is stick with one of them and complete level 1&2. It is such a difficult choice.
