Why weren't songs like 'Sorcerer' on Street Angel?

[bootylicous]

I have a question, forgive me if this has been discussed before:

Much has been written about how in the late 80's and early 90's Stevie Nicks' addiction to Klonopin left her uncreative and with a bad case of writers block, and Stevie herself says that the Street Angel album is not very good. I'm just wondering why she didn't just use this time to pull out the "vault" songs that were around at the time, such as 'Smile At You', 'Sorcerer', 'Planets of the Universe', 'Running Through The Garden'?

It seems like no matter how drugged up Stevie was at the time she still could have made a killer album with songs like these, instead of songs like 'Greta', or recycled lyric songs like 'Destiny', or covers like 'Just Like A Woman'. I wonder what she was thinking?

Cheers,
Evan
