Playing multiple sounds in order?

I have a project I'm working on that requires a continuous song of about 30 seconds to one minute to be played, it would have to be of multiple sound files. Does anyone know of a script that can accomplish this?

I've spent hours trying to work with that script, and it always ends up with the same problem of either failing to play a certain file (ie plays 1, 2, doesn't play three, plays four, etc...) or playing a file multiple times. I've tried various things, such as substituting a 'filler' sound at the place it seems to be skipping and most of the time it just ends up skipping a file in a different place, or playing 9 seconds of silence at that point.

I'm at my wits end as to how to play these files. I've seen objects before that were scripted to do it, so it must be possible, the big question is just how...
