Hello how may I help you? I'd like some help learning a world record. Sure, which record are looking for in particular No pun intended but I am seeking to learn what is the best selling record of all time? Hold on for a sec, let me look that information up Answer is Eagles their greatest hits 1971-1975 with 29 million copies It seems as though that figure would be US sales only ? It doesn't sound like very many. Yes this is figures for the United States I think they judge differently since the internet and now count downloads as sales or something like that. Do you know anything about that? A little I am not well versed on the issue I myself have searched for that and it seems difficult to find consistent answers for it. Sorry, I can not provide with the answers you looking for That's alright I know the number one selling album in USA now. Okay, have a nice day
