After clearing the cache, the preview music is also cleared. Changed the file path of the cool dog, so that the cool dog can't find these songs, and it can be solved by adding a song folder. The song folder has been deleted, only temporary files or lyrics files can be seen, and can be downloaded again.

Cool dog music itself is a music playing platform, and the platform has been responsible for making and contributing music. Later, in order to enrich the huge resource pool, I bought some relatively large original cover music platforms, which are masters, not only rich in resources, but also many fans. Of course, I have also experienced some exploration. For example, Cool Dog provided users with the function of music uploading and sharing in the early days, but later stopped and bought a high-quality music platform instead.
