I haven't had a chance to buy this latest EP yet, but the difference between the kick waves of one from yandex sample and the one on Tanzen EP (based on the youtube track) is very different.
Probably because they have a different equalization. In itself, the songs have a slight difference, minimal, but when you compare them together you can appreciate it (apart from what you can see in the waves).
Also note the difference mentioned by renonskaro.
