I've blogged about this before but I feel compelled to mention again: recent policy decisions threaten to kill internet radio. This policy will go into effect in two weeks:

This decision has the very real potential to force the closure of a wide realm of online webcasting sources that have significantly impacted the growth and development of independent music across all genres.

Sadly on May 15th we may once again lose what took us so many years to rediscover and recreate - a vital, thriving independent music scene that places value on creativity, innovativeness and originality.
