You'll need to install song packs. There are well over 80000
songs available.
Here's some useful links:

After you download a song pack unzip it and put it in
/usr/share/stepmania-5.2/Songs/.
Hints:
* To set full screen, go to "Options" and then "Graphic/Sound
Options". Then select full screen and then your resolution.
* To use USB dance pads:
Plug in your dance pad(s) and then launch the
game.
Go to "Options" and then "Input Options" and
then "Advanced Input Options". Change "Auto Map Joystick" to
off.
Go to "Options" and then "Config Key/Joy
Mappings".
Use the arrow keys to
navigate to an option, then hit enter, and then hit the
corresponding button on your dance pad.
I just set the "Primary" fields
for Up, Down, Left, Right, Select, and Start for P1. Then I did
the same for P2 my second dance pad.
