Why was Street Angel ignored?

[RockALittle250]

Looking at the tracklisting for Crystal Visions here are the number of songs per album:

Bella Donna - 4
Wild Heart - 2
Rock A Little - 3
OSOTM - 1
Street Angel - 0
TISL - 2
Fleetwood Mac - 4
New - 1 (Rock And Roll)

Of coarse, we all knew when this tracklisting was released that SA was ignored, but why? I just don't understand why she would not choose 1 song from that album, i mean, what about MLWCYM, that song at least charted. It's just weird to me that she would totally disregard that entire album for this new release...
