Thanks for the solution of the mp3 issues in my map, i used your method to remove the metadatas. And it worked perfectly. Thank you very much for everything. If you're interested you could try my map, the songs of the current version don't work on 1.30. But if you have an earlier version than 1.30 everything will work. I will soon upload an update for my map in which the mp3s are working for 1.30. Greetings
