Audio-hangover

The after-effects of listening to your music too loudly and/or for a long period of time.

The biggest symptom is a large headache, which may or may not be pulsating to the beat of the last song you were listening to. However, other symptoms are likely to occur, depending on what type of music you were listening to, as well as how you were listening to it (for example, you may feel slightly dizzy after listening to metal and hxc, due to headbanging)

Person 1: Dude, I think I listened to too much dubstep...
Person 2: You gotta cut back man, those audio-hangovers are deadly.
Person 1: I know, I think my brain is still vibrating...
