Ok, not the entire world, but from Europe. Europe his an incredibly vibrant music scene, especially the Eastern bloc & Greece. If you get tired of listening to the same 10 groups you have been listening to for the last couple of years, take a look.
I have started to write about what I have found here. This is just a start. My favorite is Russian pop - I don't understand a word of it but it sure is pleasant to listen to.
So if you are looking for a nice break in the day, come take a look a A World of Music. But all that matters is if it's for you. And please check back - I haven't even started my pages on Russian pop and I have a lot of songs to add for it.
