So this is not exactly music IN T2K, but if you are looking for some music FOR T2K, I can recommend Lao Che's Warsaw Uprising concept album. We saw them open for the Cranberries in Lublin and they were excellent.
The energy and Polish really gets you in the mood. Czerniaków has a nice eerie feel to it.
