how could the person(s) responsible for 5.1 surround mix screw up it up so bad? this was one of rocks greatist albums, now in 5.1 dts format it is a sad joke. i couldn't believe my ears! the tape hiss from the front right end of the mix is unexcusable. did the person remixing pretend it wasn't there? and what were they thinking adding the phase-shifter to Santana's guitar during the Black Magic Women outro? hey dont get me wrong, i'm one for dynamic surround effects, but this stuff is rediculious! the overall sound is thin and sometimes sounds like its coming from the next room. be warned this mix is awfull. the slick guitar feedback that segways into Oye Como Va was also tampered with. please Sony take another crack at this masterpiece.
