Well, don't confuse the two issues. I think it is entirely plausible that Strait has outsold the Stones, but as I said elsewhere, the RIAA certifications are potentially sketchy.
To repeat from the other thread:It's my understanding that bands have to resubmit their records for "recalculation" (that's not the right word, but I can't remember the correct word); it's not done automatically. There were rumblings not too long ago that Peter Criss and Ace Frehley were going to sue (now that they have been bought out of the Kiss organization) to, among other things, get some of the early albums recertified. The first three records are "only" gold, Alive! is "only" gold, and Creatures is "only" gold. Especially Alive!, wildly named as one of the best live albums of all time, it strains credulity that it is only gold. I don't know what the legal agreement is - and that's very important - but the rumor is that Gene and Paul aren't interested in recertifying because it would mean additional payments to Ace and Pete.
