Record labels aren't required to report sales to the RIAA. The RIAA only goes by what is reported by companies, they don't check it themselves. Motown was notorious for not reporting or under-reporting sales. Sometimes Berry Gordy would give acts a fake record sales plaque, which was just a regular black vinyl record painted gold. Prince said on Tavis Smiley recently that he doesn't know how much his records had sold when he was on Warner Brothers, only what they told him. James Brown has said when he was on King Records, a lot of his singles sold more than what was number one at the time, but because King didn't report sales as they didn't want to pay James, his records would hit only the lower sections on the hot 100. Record sales are never accurate anyway. Multi-CDs or box sets are counted as separate albums. So if someone only sells 1 copy of a 4 CD box set, it is counted as selling 4 copies, not 1. Even though it is really only 1 "album". Albums sold through clubs like Columbia House (12 albums for a penny) aren't counted as sales. Cut out records aren't counted as sales either. Most mom & pop stores don't have Soundscan equipment, so those aren't counted either. Some mom and pops purchase albums to resale from another store like Best Buy, instead of a wholeseller. So, if the 2nd store has Soundscan, the one album is counted as 2 sales. Today, there's downloading which are not counted as sales because an actual physical item (CD, record, cassette, etc.) is not bought. Bootleg albums, albums stolen from pressing plants, promotional copies that are sold in used shops, and used CD's are obviously not counted. So reported sales has never meant anything. Only what the record company wants it to be. It has always been this way for various reasons.
