NPR : ALL SONGS CONSIDERED

I have been tuned into this program online for the past several years. It has provided me with a wealth of indie, low profiled, less-commercially oriented performers and music. Music by diverse performers such as Hem, M Ward, and Ali farke toure are featured. I quite like the mix. I am wondering if there are others who share my taste. And more importantly, I am wondering if there are other similar sites online that provide a wealth of interesting music?
