You could also take it a step further and give the words metadata to allow you to create genre specific (or genre bending!) music. Words like brutal, blood etc are general words common to all genres. Then you could label for example moon, nightshade, frozen as "black", while tits, chainsaw and zombie could be "grind".

Step two is to add a bunch of other descriptors which can be combined with the genres - filthy, capitalist, cowboy could be "political" while despise, alone, kill, could be "misanthropic".

Allowing the user to create for example political gore grind:
Capitalist zombie tits
Spraying workers' blood
Hammer of the undead left
Chewing Marx's eyes

Socialist zombie feast!
Socialist zombie feast!
Socialist zombie feast!
Socialist zombie feast!
