I suppose there are some lyrics in that genre of music, but it is usually just a random phrase repeated over and over. I am still torn on this subject, because despite liking many songs I hear, if my headphones ever came out and the music I was listening to played out loud in public I would be embarrassed of it. At least I haven't encountered foul language with this type of music. Just random phrases like "The weekend starts here" or "we got a winner" repeated over and over.
One advantage I have to listening to this kind of music is that if (when) I become a spy and am captured behind enemy lines and they try to wear me down and break me by forcing me to listen to techno music for days on end, I will have built up a resistance to it's mind numbing effects. I'm not really gung-ho for it or going to start any clubs, but I like it enough to feel a little guilty. Lately on Pandora I have been listening to stuff ranging from Moby, Infected Mushroom, Propellerheads, Fat Boy Slim, The Crystal Method, Juno Reactor, etc.
Writing about this topic brought back some memories to an old Home Star Runner segment which I have attached. I'm afraid I can't hold a candle to Strong Bad's interpretation of techno music. http://www.youtube.com/watch?v=JwZwkk7q25I . I strongly suggest you click on the link.
