I'm still having a hard time grappling with this. In the old days of double counting a double album for RIAA certification....double albums actually cost nearly double a single album cost. Using the number of CDs as a multiplier was justified.
Today, it seems like the double-CD rule is getting abused by the various Walmart bands, in order to chart higher. Garth Brooks sold 5 CDs in a box set for 20 bucks, The Eagles are certified tripple platinum for a multiple album sold at 11.99.....and Journey is now past gold and 2/3 the way to platinum for selling approximately 300k units at 11.99.

Now, I'm sure people will gripe that I'm just bitching because thats what I do...and go ahead, claim all you want. But I find this rule to be not-only atiquated, but abused....and I submit that a FAR better way to measure album sales in this context, is to determine a weighted average price point per CD. The reason I feel this is more apropriate, is that price is the only measurable primary driver of CD sales.
Today, an artist can slap another CD or even a third dvd into a 'package' for very little, in comparison to the total unit cost of the CD package. So the artist can either cut additional tracks in a home studio, slap together a DVD, etc...and partially circumvent the traditional RIAA certification process.
I'm sure someone will pipe in with the 'thems the rules, everyone has to play by them'....but the fact still remains that 20 years ago, independent albums (or these profit sharing deals with walmart) didn't have the distribution of a walmart (or other retailer, like starbucks)....so how does an artist who was certified 2x or 3x platinum back in 1994 feel, when The Eagles can pull off a 3x platinum album by shipping 1.5 million units!??!?! Same goes for an artist that worked damn hard to get a regular platinum cert, only to see Journey pull it off with an undercut price and only 500k units shipped.
I'm not ragging on Journey here...I'm just thinking out loud that a weighted average cost/unit, given todays walmart/alternative retailer pricing, is a FAR better way to get not only a CLEAR picture of an album's success....but a FAIR representation, in line with historical certification.
