Well I can't read with ANY noise going on, without severely reducing how quickly I read... Music is just something I chuck on, but I can work with it on, if not a little slower... Studying is useless with music simply because my mind is in two different places, meaning I forget half the stuff I am trying to study.
I don't find it difficult to listen to specific things at specific times, but I find it really difficult to get in the 'mood' to write a review or something... I get some mental block or something if I am listening to the music at most times and trying to review it... Pretty weird
