I reckon these are good here, as they are literally packs of 12"'s. I wouldn't kick up fuss if they were also found on LP World, though - such is the messy and disorganised nature of life.
Yes, Earthspark please do feel free to add any similar packages here.
Hmmm not sure really, It's not marketed as a 12" pack but the various mixes are 12" mixes and the layout of the vinyl is like a 12" would be but with three of them in a pack. If you think it's better to put it on album world then I will unless anyone else has any better ideas :)
