This looks like it is sold under different CD id:
- In USA by NorthSide with CD id: NSD6063 (I think, please check if you have this CD)
- In germany by Westpark with CD id: 99542 (I think, please check if you have this CD)
- In sweden by Mass Production with CD id: Mass CD-87
They also have different covers, check NortSide and Garmarnas web sites.
I don't know if they are different in any other way. Might even be mastered from same tape, for all I know. Someone have to ask...
