I started to compose more than ever, and some of riffs I composed are on the edge of my abilities, so I needed to practice some of them for a week or so, to be able to play it at the speed I wanted. Since than I'm not interested as much to play other bands songs, except some riffs that I like. so if I stop playing other people songs, and practice my own, can it harm my playing, or creativity? Considering that I don't know many whole songs, because my practice time is devoted to techinque (maybe 20 or so)/
We learn by imitating. Transcribe, play what other people already have played, give your own twist.
