Actually I’ve been thinking the same thing a few days ago.. im not saying that all of todays music is crap, but the majority is :/

Actually I found trance music has several benefits, and I use it / ~ listen to it in cases of emergency (deadline). The so called music is very rhythmic which allows you to enter a fast work passe, and its very boring which allows you to concentrate only on your work
For me anyway caffeine has no effect, and if I have to make something done over night it can only be done with that kind of music.
