Oh tell me about it, it's so hard to expand into other genres using online services.. Noiseblend is no better at it since it relies on the same data.
I mean, in its 30-50 recommended albums, one might be just the one I might be looking for, but how am I going to find it? Am I supposed to sit through 29 albums I don't really like, just to find that?
That's why friends are the best here, they act like impromptu curators :)
But on some occasions, I find Noiseblend useful when I hear a song at a cafe or restaurant or some friends' place, "shazam" it, then put it through Noiseblend and get dropped into a musical area I might have never looked into otherwise.
