Past Masters vs Rarities   Im creating a chart for my own use that includes US albums since there are so many differences in the early albums As a US fan Im faced with the issue of whether to have US albums UK albums or both on my iPod I will post my chart on my talk page so that others can judge whether its 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 UK and US of each song  I notice that a number of UK songs are listed as Past Masters when they actually first appeared on Rarities  The Beatles album I dont 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
