Spotify software translation localization

[YugoSoft]

Hello everyone,

First of all, I apologize if I am writing in the wrong category and please move my post to where it belongs.
Spotify came to my country, Serbia, as well as to the region 5 days ago, which our community welcomed with joy.
In many ways Spotify is better than the competition. However, one thing stings the eyes. The software is not translated, localized in the languages of
the people in the countries you came to. However, Spotify was translated into Russian much earlier than you will come to Russia.
Since I am a very experienced software translator, I am interested in who is responsible for localizations? Is there a possibility to contact someone and
be granted access to translation resources? I would like to translate your applications into Serbian. All your Google ads are in Serbian, but the apps
are not. This can mislead users. I would like to help with the translation and I look forward to working with you in advance.
