1。 The album cover can be downloaded by google, and the songs in it are basically embedded in the cover, so you don't have to add the cover yourself when you synchronize directly.
2。 Manually adding is to right-click the song-Show Introduction-Cover Page, and then paste.
3。 You can also click the fourth up arrow from left to right in the lower left corner of the picture (select the song to be added before) and paste it directly.
4。 It is recommended to use the Green Apple Player (this is a software, you can figure out how to use it yourself, and it is suitable for adding many covers. ? )
5。 To use the functions that come with itunes, you must have an account before, and there is little support for Mandarin.
All methods are over!
