It's sonification of data, ICAD are the group for it. Typically the
data is "mapped" in some way to produce an audible output - this may
be done in hardware and real time, for example in the case of Stephen
P. McGreevey's VLF recordings, or in software and off-line.

It can be very useful to determine features in the data set which may
not be detectable in other ways. It may also be beautiful, depending
on your definition of that.

It is important, as others have hinted, to be precise with the
terminology, ie this is NOT what DNA sounds like, but it's a
particular representation of that data set in sound. The "sounds"
from stellar bodies is typically a linear frequency and time mapping
of the electromagnetic spectrum. It can get interesting when the
mappings are non-linear. There is so sound in space, we all know that,
there's not enough gas molecules to transmit it. All of our sound
stays on earth.

I don't think it's completely worthless, it can be pretty entertaining
and I find it _potentially_ useful for musical material - much of
algorithmic composition is based on mapping from one data set to a
sonic representation. But it also does not fit my definition of
composed music, which by and large is my preferred listening.
