Game Released: 2002
Composer: Harald Riegler (JoWood Austria. He now is the CEO of Sproing. He put the webadress in the mp3 comments)

Song Information: The are the 12 Songs that play in the Background during the Gameplay. They are all very relaxing Rock Tunes (with the Exception of the Menu Song and the Song fro the Add-on).
I can say, that if you liked the Sim City 4 Soundtrack, orlie relaxing Rock Tunes without Lyrics, that you shopuld at least give it a try. Here are 2 Preview Songs:

Laid back: Industry Giant 2 OST - Laid Back - YouTube (http://www.youtube.com/watch?v=YPK9RIGrDPc&feature=related)
A New Start: Industry Giant 2 OST - A New Start - YouTube (http://www.youtube.com/watch?v=JI9R7Pk8KYs&feature=related)

Technical Information: The Numbering of the Tracks was strange, so i just left the Numbers there and wrote the Tracknames behind them.
The Tracks have a relatively low Bitrate of 192 Bits/s (3 of them only have 128 Bit/s)
