BT-STS: BIT.TRIP SOUNDTRACK SAMPLER

[ᄐv๑–X²]

Received my copy today thinking there's a slip case, only to find a hinge in the case. Back of the disc reads as follows:

-"BT-STS" (Acronym for Bit.Trip Sound Track Sampler)
-"arvato digital services - Bertelsmann" (CD Publisher/Pressed?)
-"74072222" (???)
-"IFPI L027" (This is printed 2 times on the disc)

Does any of this indicate a catalogue number? I'm nudging its the last one. Discuss...
