"COMPILATION = Unofficial field that is only used by iTunes/iPod to mark albums as sampler."
I am no Apple lover
Normally I do not use this fieldtag, because my other mediaplayers do not need this to mark albums as sampler.
But the compilation field "1" does not bother me either.
In some specific cases I use this fieldtag in the "opposite way". I enter the value 0 to mark an album as no sampler.
So I have voted yes.
