Record labels from the former Yugoslav nations all have their archives available digitally, even the labels that are no longer active, so why don't Bulgarian ones do? I learned from my other Bulgarian friends that this is either because:
1) Labels destroyed or lost their masters
2) Many labels simply do not care
3) Copyright (which to me doesn't make since since a lot of turbofolk songs are plagiarized too and they're still available to buy on iTunes)
4) Rumors about someone stealing the masters
And I found this to be so sad, and even if you reach out to the artist themselves, many of them don't even have the masters to their own content, and this doesn't stop with chalga, lots of estrada and retro pop music are like this too…
