Im insane i play dimmu borgir's songs while homeworking,homeworking is different thing though but when it comes to studying(which i must now that i am science student) i play some OST's...the soothsaying melody perfectly synchronizes with studying rhyme...maybe you should try some soundtracks
try Meet Joe Black (1998) OST
i downloaded the tracks from internet who bothers to buy,it's not even available in place i live so call it excuse or call it no other option...i don't really seem to care

the tracks i have are random some are even false;they were never featured in movie..
Whsiper of thrill,walkaway,somewhere over rainbow,that next place are cool healing tracks....i think perfect material at study hour
