This year's U.S. music sales would be almost uneventful if not for the "Frozen" soundtrack. Purchases are down across the board -- even digital albums and tracks. Releases by superstars have stumbled.
One album has bucked the trends and is doing brisk business, however. Through July 13th, "Frozen" leads all albums in three categories: share of track sales, share of album sales and share of track-equivalent album sales. A track-equivalent album, or TEA, is a measure of an album's popularity that combines album sales (in album units) and track sales (track units converted into album using a ten-tracks-to-an-album conversion metric).
The Disney soundtrack has a 2.15% share of album sales, nearly four times the 0.55% share of second-place "Beyonce" and over four times the third-place album, Lorde's "Pure Heroine," according to Billboard analysis of Nielsen Soundscan numbers. "Frozen" has topped the Billboard 200 album chart 13 times and has sold a total of 2.78 million units.
