Downloaded to safe and sound MP3

I want to download Taylor Swift's safe and sound (mp3). After searching for half a day, I finally found it in songtaste. When I click Download, it tells me that the "Multi-meter player" must be installed before it can be downloaded ). Of course, I still need to click Download, so the following address appears in the address bar:

Duomi: // T = O & AC = D & U = http://media6.songtaste.com/201202270702/d35b818d85aedef5be99a4db21fe92d1/6/64/6456e46b3226af1ac01ec73b58694578.mp3&sn=c2FmZSBhbmQgc291bmQgsLLIq87e7aY=

So I want to tell them that since we have designed a protocol, we should at least learn about the thunder express and so on. We can also process the resource address with base46. That shiny HTTP makes me happy. Copy, wget, and download a song.

This type of situation is estimated to exist in many websites. As long as you know the file structure of the website, many websites can skip the front-end restrictions and directly access resources. Many people do not have permission to set them.
