yes, may be you're right
Greg..may be a fake when i listen to it with moree attention...don't know ...found it : it what the number 12. of an album which count 19 tracks and which is called
"Serduchka & Glukoza - Zheniha.xotela "The fist song is "Zheniha.xotela " with the duet Serduchka & Glukoza and then there are different songs from Serduchka and Glukoza singing alone...the titles are for exemple.."Nenavizhu"...so real songs from Glukoza...
So or it's a personal compilation or it's an official special edition with songs of both...
Their single seems to have been a success , so may be their producers decided to release this album...an enigma...
Just see that "Goryachaya" orr "Gorjachaja"...do you see a relation, a link with Glukoza?
