This article does not have any technical content, it is just a chance discovery. It is known that QQ Music API does not restrict non-copyrighted songs, it should only be restricted on the client side.
Knowing the songmid, you can play almost any song, except for VIP songs.
It's not a big problem, it probably won't be fixed for 114514 days.
I discovered this issue in 2021 and provided feedback to QQ Music about the problem of playing non-copyrighted songs, but the issue has not been resolved until now.
I should try to salvage the cover songs that have been taken down, but it's a bit troublesome...
Recently, while I was listening to music, I randomly came across this:
Because I had previously searched for songs by ES, since 2023, Tencent has only had a few dozen songs with copyrights.
This doesn't make sense, shouldn't they be without copyrights? Why can I still listen to them?
All the following tests were done using the latest version of the client.
In the client, you can only play songs that you have liked or added to a playlist, the API does not have restrictions
QQ Music UWP#
Download speed is too fast, couldn't capture it
Clicking on an album shows no copyright
QQ Music Mobile Version#
Playable, downloadable, smart scores cannot be played
Opening an album shows no copyright
Smart scores cannot be played after the countdown
QQ Music PC Version#
Playable, not downloadable, smart scores cannot be played
Shows copyright, playable
Download menu can be displayed, but
Download prompt says the service is not available
Smart scores prompt cannot be played
Reproduction with Postman#
You can use Fiddler to capture packets in QQ Music UWP, it is very useful
Then fill in the cookie, copy the request body and modify the songmid
Modify it to another song without copyright
Search for https://c.y.qq.com/v8/fcg-bin/musicmall.fcg in the album page f12 to find songmid
Of course, not all will be successful...
