Opensim is such a great multi media and multi reality place and here are a few items that prove that statement. It's a great way to learn about other cultures and languages and ideas, so be sure to get out there and explore!
First of all congrats to Art Destiny radio which is 2 years old this month! 
It's a radio station with commentary by three opensim friends, Richi, Genie Fegte, and Loru - plenty of great music, great chat if you know German or want to practice listening to German and improve your accent, and either way a great choice for the soundtrack to your sim, perhaps. It's a fun way to bring together the diaspora of small grids with a people who know opensim inside out.
Give it a try! Here is their latest promo, which you can also watch on Youtube of course - and if you watch it there you can Like, Comment and of course subscribe to the channel.
