Scene with stereo system playing?

And hopefully people being aggrivated by it.

There's a few stereo scenes in E7.
Episode 22: Some rave party was happening in the middle of nowhere.
Episode 17: Blonde-haired guy cranks up an old yellow stereo, and the guys around the stereo are bored because of the terrible music playing
Episode 30 (I think): The Head Scientist stops everyone from their work by playing eardrum-blasting music around the whole area. While the employees are partying, everyone else who isn't involve either has their hands cupped over their ears, or is just aggrviated in general with it (eg.: i nthat episode, Holland, lying in bed, hears it and complains about how old-fashioned the music is.)

Other than that, I'm not really sure. ^^;;
