Really feel like this highlights how the OCC's methodology of how individual track streaming contributes to album units - counting streams to two albums (typically a parent album and compilation) - is swamping the weekly and year-end charts with compilations that effectively just reflect plays of tracks from elsewhere, not the popularity of the compilations themselves.

Only allowing tracks to contribute to one album's units and using Billboard/Luminate's system of counting streams of a track towards whichever album said track is on that recieves the most pure sales during the tracking week could help to reduce the sheer level of stagnancy that certain compilations have given they're only really reflecting the popularity of the artist's catalog rather than the albums themselves (MJ's The Essential isn't even the best-pure-selling MJ compilation at the minute, the label have just requested streams to be redirected to it from Number Ones).
