Comment:
Operating systems don't work like that: they do not have access to other
processes' memory (or address space).
What you're observing is the kernel struggling to keep memory available
for all the programs you are running, and possible, the effect of swapping
memory from ram to disk. In particular, real time programs, like music
decoders, will stutter and fail to keep it together when there's a lot of
contention for memory.
In summary: don't try to allocate really big files while running music
players, unless you expect interference from the operating system as it
juggles all the work you're giving it.
