Remember the days when you could tell someone you liked ‘alternative’ music and they would know that you probably liked The Smashing Pumpkins? Those days are long gone. Today when someone asks what kind of music you like, you need to start naming bands to give them an idea (or lie and say you only listen to The Velvet Underground). The above image is a heatmap of last.fm tags for The Black Keys from Music Matrix. It gives a good overview of the terms used for a particular band. We recommend heading to the site and checking out the tag heatmap of a few of your favorite bands.
