Ubuntu Multimedia :: Simultaneous Application Launch In BASH?

I'm trying to launch CoverGloobus (a fantastic little album art and current song display) and Rhythmbox simultaneously through a BASH script. Problem is that when I attempt to run the script the first time, CoverGloobus doesn't launch, but Rhythmbox does. Here's my script as it is right now:

Code:

#! /bin/bash
#Opens Rhythmbox and CoverGloobus
rhythmbox && covergloobus
done

I've double-checked the commands in gnome-terminal, and they're the right ones for launching the applications. Here's where it gets odd, though. The second time I run the script, CoverGloobus and Rhythmbox launch simultaneously. I've reproduced this scenario multiple times.
