Argh... I have forgotten how to put midis into levels

. I know you used the play or playlooped command, but the file I want it to play isn't playing.
I seriously have forgotten what to do... this is what I have done but it doesn't seem to work.
if (created) {
play home.mid;
}
The above doesn't work, but alter it a bit...
if (created) {
play stef1.mid;
}
That one works. The home.mid is in the same directory as stef1.mid, and it is a valid MIDI file. What am I doing wrong?
