I listened to the albu mthat song was from and omg it's amazing!
youtubing her other stuff now omg I needed new turkish stuff, lol.
and back on topic: I know that it's common for remixers/composers to use samples from a common source, but ofc I can't remember what it's called. It's especially common in DJing, artists like Nakata do it all the time with their stuff. There's stock vocals/compositions that are for free use and don't need to be cited. I think at least definitely in tasking's case that seems to be the issue.
