Not that I can claim that I know what I am talking about...but...
From a early article in Byte on the NeXT I seem to remeber the memory
that the DSP has is quite limited.  I would guess that the 68030 has
to swap in new data all the time.

Isn't the *only* reason it was installed was for 'CD' quality sound... wasn't
the 030 supposed to handle the tasks?

Working on release 0.9, I am amazed every time I log onto it... just wait
until it gets to 1.4...(isn't that the magic number??)

Another thought: How many songs do you want to hear concurently? 

PS: see you on comp.sys.next

Since I don't think Mr Jobs will be able to reply I felt someone should
offer a little reality.
