I agree, this feature is pretty much essential for anyone who bikes, runs, or drives a lot. Voice commands are the only thing I miss about my old iPod. It would also be great if you could do this based on ID3 tags, rather than by search terms. For example "Listen to Album: '<album name>'." This saves the confusion of having a lot of self-titled albums and title-tracks on albums. It still seems a little strange to me that Poweramp is one of the more expensive music apps and still doesn't support voice commands.
