I am not a techie user, but I feel like it is weird, if it was an open source website / service I would not be so spooked out, but Jamendo is NOT open source, afaik,
I am not gonna use it for now, while I try to figure it out, but I felt like I had to point it out.
AFAIK Jamendo is still exclusively serving Creative Commons licensed audio. The website is a mess compared to what it used to be but I don’t believe that has changed.
So I would think of it as a bug and probably report it though I do not use the program. Jamendo is fine but I also do not want some random feature being enabled on my apps.
