Educate me, why are 2 disc albums so common?
I have some albums that manage to get themselves on 1 disc (2 sides) but it seems so many others with the same or less run time need 2 discs (4 sides)
For example Straight Outta Compton (NWA) is an hour long and fits on 2 sides whereas Pyschodrama (Dave) is 51 minutes long and uses 4 sides.
Can anyone explain why this is the case?
Furthermore, why do the discs with less on, Pyschodrama in this instance, not require being played in 45rpm?
