I know what you mean.I have always suggested listening to something a bit different or trying something you may not have done-for example, I had a go at slide a while back and it was something I had only dabbled in previously.I am no expert but I can get away with it now and I found myself listening to stuff I would not have done otherwise and loved it.Obviously it has to be music you like otherwise the enthusiasm for learning just aint there. I am no lover of country music but I "discovered" Danny Gatton years ago as a result of looking at it objectively.Some of the country players give shredders a run for their money. No help, of course, if you have tried those types of music but you get the idea.
