First-week sales of Christina Aguilera’s Target-exclusive greatest-hits package Keeps Getting Better, which contains two new songs and two reworkings of old tracks: 73,000. Single-week sales of the title track, which also happens to be one of the two fresh entries on the album: 63,000 (it’s sold 479,000 copies to date).
