Unit sales for Albums priced below $3.49 during their first four weeks of release will not be eligible for inclusion on the Billboard album charts and will not count towards sales data presented by Nielsen SoundScan.
*The rule also applies to reissued titles.
*New Holiday/Seasonal titles must meet the minimum threshold through the final week of the calendar year.
*Unit sales for albums or EPs with 8 or less tracks will not be eligible for charting if the retail price is less than the sum of the tracks on the release, multiplied by $0.39.
*Minimum pricing for a multi-disc album (not a single disc with extra tracks), where the extra disc is audio content, will be $3.49 times the amount of discs being made available.
*For digital-only deluxe editions, any extra content exceeding nine tracks would be considered the equivalent of an extra disc. Each additional 10 tracks thereafter would be the equivalent of an additional disc.
Unit sales for Digital Tracks priced below $0.39 during their first three months of release will not be eligible for inclusion on Billboard's digital songs charts.
