@firekorn Yeah bringing those tags into ignition would be the best way. Then you don't have to worry about the genre being too broad nor too specific. Just browsing metal type "metal." What "Swedish post-deathgaze?" Well the charter might have tagged it so you can try your luck search.
I'm add my voice in saying I'd love for a tagging system. Let registered users add tags like "post punk" "japan" "soundtrack" "video game." There's so much CDLC and no way to sort through it to find something new and interesting unless you already know the band you're looking for.
