i'm doing some compressing work for music and before i tackle some songs i would like to check and see if they are in blockland's cloud cdn or whatever the stuff you want to call it. it is my understanding that even downloading super compressed music from a bl server is slower than downloading the same uncompressed music from the cdn because the cdn stuff is way faster than direct downloads from a blockland server, which is why i would like to know how to check the cdn before i compress some of this music
