What makes some music unavailable in some countries?

[FluxSpirit]

Why is some music not available in countries? Like it doesn't make any sense, why would they not release it in some?

[user-removed]

yea why do they do that...?

I guess this has to do with the main distribuiter company in the Country, the management contracts they have and even the marketing campaign planned.
Same thing happens in the itunes store. The Content is different in each country
