A friend of mine has started a "new" EZ/BM station online called Hits on Guitar. I say "new" because he originally had his station for a few months on loudcaster until their service folded, but has since brought his station back online. It is guitar-based instrumentals of mostly pop hits, with some harp and flute pieces added as well. Here's the listen link:
