Which remasters to pickup?


Ive got a few old cds that that have since been remastered. I want to know which ones are worth picking up.

Sly and the Family Stone-Anthology Remastered
Cream-Remasters
Led Zeppelin-Remasters
Santana-Remasters
Al Green-Remasters
Isaac Hayes-Remasters (import)

I dont have an SACD player yet, but Ive got a few hybrid sacds that sound pretty good. The Rolling Stones are the best Ive heard so far, the Police are okay, and Im anxiously awaiting the new Pink Floyd DSOTM disc. Also feel free to recommend anything in the soul/old r&b/classic rock genres.

I dont regret buying the Zeps cuz I only payed about $30 for 2 discs. If theyre as good as the Pink Floyd SACD Id buy them over. What label is the remastered LADT SOUL on?
Do you know if Aretha sang "Can it all be so simple"?
Sony has released a number of Santana CD's in the last couple of years, probably due to the success of the Grammy sweeping "Supernatural". Santana's Greatest Hits and Abraxas are 2 that I bought and both are excellent. In fact, I recently bought Abraxas on SACD and don't think the SACD layer is any better than this remaster!
"lady soul" is on stax/atco reissue series...as are the Otis redding releases...
RE: Santana remasters... Now, if we can only get them to remaster "Supernatural" (too much compression on the original release -- sounds great on a boom box, awful on a high rez system).
