All New World of Lemmings (E) / The Lemmings Chronicles (U)

Track names are based on the file names from
the Amiga version, since they don't seem to
have any titles anywhere else.

These tracks were originally stored in HMI
format, a MIDI variant with looping among
other features.  Some of these tracks have
large gaps before their loops, which sound
strange but are actually present in the
original format and therefore have been
preserved.
