Contact imposes restrictions

3 days ago I could have driven Mumiy Troll's band into an audio search and found all their songs, but today I found out that there was not a single result for the Mumiy Troll query or just the Mummies query. So far from all groups, but 3 days ago it worked, but today it does not. For some of the names of their songs, the search also does not work.

PS: I'm not complaining, it’s right that the management of the group began to monitor the observance of copyright, there are simply restrictions and this has become noticeable.
