Bug I think... but it's not straightforward one to fix. The way Owen
did it he allowed playposition to vary from -0.14 to 1.14 instead of
0.0 to 1.0. For longer songs, the .14 will add a longer lead-in. The
max and min playposition would need to change as a function of the
track length but there are parts of Mixxx that have it hard-coded to
.14.

I agree it's not useful to have such a long lead-in.

I like this idea! It's common in DJ software to assume the signature
is 4/4 anyway so it's not a terrible thing to do.
