past masters vs rarities i'm creating a chart for my own use that includes u s albums since there are so many differences in the early albums as a u s fan i'm faced with the issue of whether to have u s albums u k albums or both on my ipod i will post my chart on my talk page so that others can judge whether it's worthy of including here i realize there will be problems including the lack of canadian albums my purpose is simply to record the first album appearance in both the u k and u s of each song i notice that a number of u k songs are listed as past masters when they actually first appeared on rarities the beatles album i don't know the reason for this if the purpose is to list the first appearance on an album can someone explain or should they be changed to rarities
