Before buying: songs playing at a slower speed?

Playing mp3 files from numerous sources including downloads from Amazon, rips from .wav files and CDs, swapped grey market files, home studio generated files ALL play fine on the following:

WinAmp or WMP on XP PC

CDeX

n-Track

Tascam DAW

CDR mp3CD

DVR mp3DVD

Sony NWZ-e438f

The same files ALL play slow and off pitch on the following:

Sansa Fuze

Sansa Clip

It shouldn’t take a $12000 turntable to get reliable playback (and at that price, by the way, I wouldn’t take 1%, either.)  When you spend your life loving and pursuing ‘the sound,’ you don’t accept sub-standard reproduction.  If everyone accepts this type of fault, another nail in the coffin of art appreciation will be set.  Think of it as selecting a color of paint or fabric for your living environment and finding that the manufacturer has decided that they can alter it to simplify their offerings to you.

My advice:

Don’t accept substitutions for the sound you expect.  Demand accurate reproduction.
