I really like the idea of soundscapes, Raman.

As a first approximation -- that is, before requiring a new hook to try out
the utility of your idea -- I'd recommend using a timer that checks the buffer
of the currently selected window is.

I doubt it's even desirable to change the music instantly whenever the buffer
changes; in some cases, that could become quite jarring. A timer not only
solves your problem quite simply, but allows for customization opportunities
like "cross-fading" after you know that the user has been in the new buffer
for X milliseconds. This would prevent quick Org capture buffers from
disrupting the music of my Gnus summary buffer, for example.
