Give you a method. From now on, all online music can be downloaded, and naturally Xiaoxu music can be downloaded (I tried downloading Zhu Xian 2 music and it was successful, as shown in the picture):
Use a Firefox-based browser (Firefox or Purple Fox), download and install a plug-in called downloadhelper or netvideohunter (the latter is downloaded in the picture, the former can also be downloaded). From now on, everything can be done The audio and video it smells can be downloaded (but it is best to wait until the audio and video buffer is completely downloaded, otherwise it will be incomplete).
Method: Install a Firefox-based browser (Firefox or Purple Fox), and use the new browser to go to this URL: https://addons.mozilla.org/en-US/firefox /addon/video-downloadhelper/
Download and install. If it does not automatically install itself, you can drag the downloaded xpi file into the add-on and it will be available.
