I don't think anyone has said it's the worst mastered album of all time, but it's not fantastic, that's for sure. Bad mastering doesn't always collapse the soundstage. What it often does is reduce the dynamic headroom available to the data, meaning (in English), that there are fewer levels of gradation between soft and loud. (As a side note, hot, compressed CDs are easier on amps than non-compressed CDs.)
I just gave it a listen and it may just be the worst-sounding track on the album, honestly. It does give me the feeling of a wider soundstage, but I think that's just the ambiance (natural or artificial) of the recording. The drums sound hollow and all the instruments are sorta smeared together across the front. No definition.
What are you smoking?
Try listening to that track, and then switching to anything on the Buena Vista Social Club disc, for example. The difference is night and day.
