i don't really get into lyrics, which is one reason techno suits me so well. the way i see it, in good hip-hop, the voice acts as a rhythmic instrument, so maybe some hip-hop vocals would suit techno well, but i'm loathe to see techno turn into a style of music where you are "told" what the song is about rather than "shown" it.
still...as i said in the other thread, i'm open to it if it's done tastefully. i just hope it would stay abstract and not too literal...
