I’ve been using Last fm for the last couple of months.
My musical tastes are wide and varied but a common theme with stuff that I like is that it almost involves talented guitar players. Melody and groove feature heavily too.
I find that it’s very rare these days that I find new bands that I like. The main reason I started using Last fm was to get some decent recommendations. It’s already paid me back by recommending I check out Band of horses.
If you have vaguely similar tastes feel free to add me or send me recommendations.
