Hi all!
The Beatles made 2 albums per year since A Hard Day's Night
A Hard Day's Night/For Sale
Help/Rubber Soul
Revolver/Oldies
Sgt. Peppers/Magical Mystery Tour
White Album/Yellow Submarine
Abbey Road/Let it Be
normally, one was for summer time and the other for winter time
now, you have to compail albums from 1971 to today
a album for Summer 1971 and other for Winter 1971
a album for Summer 1972 and other for Winter 1972
etc.
Cheers!
