Hola, RugaL, quizá debería de haberlo explicado antes. Las ventas de los clubes de música, básicamente, son aquellas que no se han producido a través de una tienda física, abierta al público, sino de un llamado 'music club', que te lo envía por correo (y generalmente con cierto descuento, al estar suscrito y comprar varios títulos). En los 90 fueron altísimas, hoy muchísimo más bajas. Soundscan
NO las recuenta y la RIAA sólo las tomó en consideración para los certificados (o recertificados) desde mediados de los 90 (pero con efecto retroactivo). Ello explica la enorme diferencia, en algunos casos, entre los datos de Soundscan y la certificación de la RIAA, a no ser que esta última quede anticuada, como ocurre, por ejemplo, particularmente con los discos de Janet Jackson.
Te copio una nota publicada por BMG MC (que abarca el 40% de este mercado) en 2003 sobre los 100 álbumes más vendidos en USA por ellos:
Celebrating 14 years as the world's largest music club currently serving more than 20 million members announced their all time sellers today.
The BMG Music Club sold more than 300 million cassettes and CD's in it's 14 years in business, and this month will honor the clubs Top 100 Selling CD's with a special Plaque, plus all Top 100 will be included BMG's music publication issued to club members at a special discount price.
With nearly 2 million units sold, Shania Twain's "Come On Over" owns the title as the clubs #1 selling LP, Twain also appears on the list at #25 with "The Woman In Me" which has sold more than 1.2 million copies, again at #90 with the newly released "UP!" which also sold nearly a half-million copies in the 6 weeks the club has been selling the title, and at #96 with her self-titled debut with almost 400,000 units sold.
Backstreet Boys and 'N Sync prove their staying power with each boy band placing two albums in the all-time Top 10, closing out the Top 10 is Pop Diva Madonna with her "Immaculate Collection" with just about 1.5 million units sold in the music club, the superstar also appears on the list with "Like A Virgin," (#59, 822,000 units), "Ray Of Light," (#91, 459,000 units) and "True Blue," (#99, 301,000 units), not to mention her other club titles which didn't make the Top 100 "Madonna Remasters 3-Pack," (11,000 units), "The Early Years - Give It To Me," (8,000 units), "GV2," (90,000 units), "Music," (97,000 units), "Something To Remember," (179,000 units), "Bedtime Stories," (195,000 units,) "Erotica," (84,000 units), and "Like A Prayer," (244,000 units).
Another Pop Diva Janet Jackson appears in the Top 10 with a greatest hits collection, Jackson's "Design Of A Decade 1986/1996," is the clubs biggest selling hits collection from a female singer closing in at #9 with nearly 1.5 million units sold, Jackson appears on the all-time chart 5 times (with two discontinued albums from the club due to contractual agreements), at #35 with the groundbreaking "Janet Jackson's Rhythm Nation 1814," #58 with "Control," #63 with "Janet.," and #95 with "The Velvet Rope," other Jackson title's include "All For You," (100,000 units sold and issued under contractual agreement), "Dream Street" (44,000 units) and "Janet Jackson," (82,000 units).

Columbia House es el music club más importante del mundo.
Aquí se desarrolla su manera de funcionar.
Para calcular los números globales de un álbum hay que sumar fundamentalmente:
1- Ventas por las tiendas.
2- Ventas de los clubes de música (más del 10% del total en los 90).
3- Discos distribuidos por la compañía pero aún no vendidos (que también son tomados en cuenta por los mecanismos de certificación)
