Hoping the name change is legit, as Bridges in the Sky is a significantly cooler name than The Shaman's Trance was.
I can't imagine where Play.com would've got the information from. They wouldn't make it up, and it certainly wouldn't've come from any lyrics - when companies put up tracklistings, they don't listen to the CD and guess, they either get it from the source or a physical copy. My guess is that the band had a change of heart before printing, and so the physical copy no longer matches the press release.
It happens. I remember a few years back the Radio Times - the biggest TV listings magazine in the UK - were making a big kerfuffle over the fact that they had the exclusive rights to reveal the titles of the new series of Doctor Who.
Everyone bought the magazine, and pored over the titles, along with information about the writers, summaries of the episodes, etc. etc.:
1. Partners in Crime
2. The Fires of Pompeii
3. Planet of the Ood
4. The Sontaran Stratagem
5. The Poison Sky
6. The Doctor's Daughter
7. The Unicorn and the Wasp
8. Silence in the Library
9. River's Run
10. Midnight
11. Turn Left
12. TBC
13. Journey's End
...but then, within about two days of having been released all up and down the UK, circulating through over a million households - River's Run had changed its name to Forest of the Dead. The biggest drama in the UK just went "Yeah, about that? Turns out, no." Contrary to every press release and sliver of information that had hence been released. It happens! Post-publication, someone goes "actually, how about this?" and rather than leave it be for the sake of some announcement, they go "you know what? that's better, and there's still time," and so they swap things around. And you can kinda see why they'd change The Shaman's Trance. Bit of an odd name, certainly.
There's precedent. It'd make sense, and I'm not sure where Play.com would've got Bridges in the Sky from were there not a grain of truth. Even if they've maybe since gone back on it.
