Well, those sales from Amazon for Whistle won't count until July 24, because technically it is still less than 3 months of its release date. Anything below 0.39 cents for the first three months won't be counted.
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.
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.
