That's precisely why the Playlist Duration constraint exists.  Go check it out.

The reason "X number of tracks" is the default is because in terms of
algorithmic complexity, the operation "select 30 random tracks from
this set" is a lot simpler than "select 30 minutes of music from this
set".  The former is trivial, and the latter is the subset sum
problem, which is NP-complete.
