Open the cool dog software, click the menu setting option, set the general, directly add the files to be enjoyed by * * * to the playlist, restart the cool dog, and install an iTOOls software on the computer. After opening it, Apple music will systematically recommend your favorite music according to the music on your cool dog music.

The specific operation method is that there is a computer on the left. Click Add to find your music. Select the music you want to add in that disc, and then pour it in. There is a small square box under Add, and pour it into the device. Remember not to turn it off directly when pouring into the device.

Because apple music doesn't have a separate list of my favorite songs, I can find my own songs that have been clicked with red hearts in the playlist. Clicking red hearts is used to count your preferences and recommend more similar songs for you.

Therefore, the smart playlist on iPhone is like an album, which will be more and more behind the list with the increase of the number of albums in the library, which is inconvenient compared with Spotify, but it can be found in the playlist.

Red hearts are used to count your preferences, so as to recommend more similar songs for you, not for collection. If you want to collect, please click the menu in the lower right corner and select Add to List, so that the featured recommendation of Apple music will appear.
