The first method, which is relatively simple, is to collect songs and songs you like.

When you listen to it for the second time, you can look for it directly in the collection. This method does not require traffic and does not require payment.

The second method is realized by setting internal listening and saving.

Check the box of saving while listening in the settings, and then listen to a song from beginning to end, and the song will be automatically saved in the cool dog folder.
