I guess struggling R&B singer Trey Song knows who his real fans are. According to online projected sales estimates, only one third of the singer’s rabid 300,000+ Twitter followers went out and purchased his album on Monday.

Trey’s Ready is expected to push between 100-115K in first week’s sales to take the #2 spot on the sales chart. The CD will barely break 100K even with the added advantage of a Monday release. Record labels normally release product on Tuesdays.

The Diva Whitney Houston, who struggled through her live performance in Central Park yesterday, will claim the top spot on the charts next week.

According to HitsDailyDouble, Whitney’s Arista/RMG album, I Look to You, boasts an expected sales figure of 250-275k. That’s more than double the sales of Trey Song, and she doesn’t even have a Twitter page.
