Music

I've recently lost interest in most of the music that I've listened to for years. It might be that in coming back to my roots, I'm missing the world of music I experienced for so many years. Now I enjoy African and Celtic music, but I'm having trouble finding it. I don't object to buying music online, but most of it is compressed with lossy codecs that reduces the listening pleasure, so I'm forced to buy it in physical format. I can get some of the more popular artists at local stores, but most of the CDs available are compilations. I'll then find a few standout tracks and want to hear more music by the same artists (eg Lhasa de Sela, Susheela Raman and Clannad). But I know there is other great music out there that doesn't make the compilations I pick up. Sydney radio doesn't seem to have much in the way of world music. Our record stores don't either. What is the best way to find and buy high quality recordings of world music?
