Make video in iMovie with audio and title screen only (no video)?

[paulisme]

I've got an audio clip that I'd like to turn into a video so I can post it on Facebook. All I want to do is show the title of the audio clip as the video portion and have the audio play over top of it. I was able to do this with an audio clip that was less than 30 seconds long by adding a title to the project and setting its duration to the length of the audio clip. However, when I tried to do this with a longer (1:30) audio clip, iMovie wouldn't let me set the duration of the title for that long. I see people do this all the time on YouTube, so I would hope there's a way to do this in iMovie. Any suggestions?
