It appears, in what can only be described as a "shocking" development, that the rise in prices is hurting sales of the more expensive tracks, and could eventually lead to less revenue as well. These conclusions, from Billboard are only based on two days of data however, and are obviously subject to change. So far, the higher priced songs continue to lose chart positions to lower price songs.
On average, $1.29 songs lost 5.3 places on the Top 100 sales chart, while $0.99 songs gained 2.5 spots. A few of the songs that were initially $.99 on Tuesday but changed to $1.29 on Wednesday lost an average 1.9 places, while those that remained $1.29 for both days lost a huge 7.7 average positions.
The same trend was seen on Thursday with the more expensive tracks losing even more spots, an average of 12.4.
