When I looked at Active Melody and from what I could tell it appeared to be heavy on blues. Not that I couldn't find something to learn, I'm sure, but I've played blues until my blues had blues and it made my blue eyes blue. I'm definitely more interested in flat picking right now, though I've also been going back and re-learning some of the acoustic stuff I used to play, you know, the usual chestnuts by Zeppelin and Yes, etc.
For the past 4 years my job has been mainly to 'entertain' senior citizens, and pretty much all they would let me do was sing and play, every day, all day (and night). It was absolutely great for me as I never spent much time singing before that, and it was also good for my arranging as you mentioned. Other areas of my music have been largely dormant however, and since I'm out of work at the moment I'm picking those up again. I've been playing lots of piano lately too, boy did I miss that.
