So if you capture a stream you can manipulate the individual songs in the 
playlist like any others.

For local files, yes. Remote (unseekable) streams would still behave as before 
- one track whose information would change between logical streams.

I think there are only a few differences between phyisical streams and logical 
streams, so the extra work to make them right may be fairly minimal. You'd 
need to make sure that the final stream used the same serial numbers 
throughout, and maybe do some work on the headers of the second one, which 
may just mean deleteing them (or are their codebooks that you need to keep?).

I don't think relying on a physical bitstream being considered a single entity 
by player software is a good plan in the long run.
