Oh no, please don't mix up Ukrainian and Belarusian Г! I know such pronunciation is very common, I know that even some Ukrainian celebrities do pronounce Г like a Belarusian sound, but you as language learners, don't repeat this mistake! The difference is the following: Belarusian Г is the strict voiced pair to the Х ([x]) sound, while Ukrainian Г is the voiced pair to the English H sound. To make it, try saying "Haaaa!", but start with voice from the beginning, the mouth should be open (like in the word "Harmony", for example), but try to make the H voiced, and you'll get it. I love that sound, it gives the language a large part of its musicality.
