Sales
I notices that sometimes the sales dont match in the song and on the album total sales, for example
This track has some scrobbles without an album tag. On the track page, those scrobbles are included in the total, but on the album page they're filtered by album, so they aren't counted there.
For now, there's not really anything that can be done unless you edit those scrobbles on Last.fm. We do plan to solve this in the future by adding a feature that lets you assign an album to tracks directly within ZERO Charts.
