Same here....Always. I always have to have metal or rock on while I work. I lose interest in things fast (ADD) and for some reason, music always levels it out.
Not my favorite song by them, but for some reason it always gets me pumped up! :
YouTube - Metallica - Fight Fire with Fire
If you are dyslexic like I am, Baroque music has been proven to help you concentrate and focus. If I am not listening to that I am listening to some trance music.
This is the way i look at it for me. If am working very hard on something i need to be listening to something that is calm and not crazy. One the other hand if I am just drawing then i listen to rock or something that will really get me into what i am doing.
