Well, a signal in MO can express two different things: the master
signal (which will be shared across all releases of that track, e.g.
on the single and the album etc.) and a signal encoded in, say, an
audio file. So you can have something like that:
:signal mo:published_as :track1_on_single, :track10_on_album .
:track1_on_single mo:available_as :my_mp3 .
:my_mp3 mo:encodes :my_signal_with_lots_of_compression_artefacts .
Different versions (e.g. live, studio etc.) will be two different
signals (one of them is the outcome of a performance and one of them
is the outcome of a recording session).

Yes, if it is coming from the same master signal, then you'd have one
signal for two tracks. A track in MO is a track within a particular
album (hence the mo:track_number property on tracks).

I think you're mixing the "song" (the actual work - mo:MusicalWork)
and a track. A track is something which is a part of a particular
album (e.g. track 1 of Nevermind). A song is a work (e.g. Smells like
Teen Spirit), which can be performed and recorded multiple times
(live, studio, covers, etc.), in a variety of settings. All these
recordings will end up producing different signals, which may be
released as part of more than one manifestation.
