LOS ANGELES (AP) — Adele’s “25” has just reached a major sales milestone and could shatter an all-time record. It’s sold 2.3 million copies in just three days, according to Nielsen Music. It’s only the second album to sell more than 2 million copies in a week. The other album is the record holder: ‘N Sync’s “No Strings Attached,” which sold 2.4 million in its debut week in March 2000. The final numbers will be reported on Sunday.
