Updated music information is getting deleted

[Sureshg1988]

In Xperia L we can download the music info from web by using "Download music info" option.
After disconnecting the USB cabile from PC, the updated music informations (like album art music info) are getting deleted

and the old album art and music info is replacing the new one.

How to make the updated music info as permanent?

[Uliwooly]

Open the walkman app > menu > download album info 

or 

on your PC > use WMP > download album info > THEN transfer the music to your phone

or 

transfer the music with Media Go 

or 

Use an app such as albumgrabber

It doesn't save that info by editing mp3 file. It is just saved in walkman player. Use mp3dit or tag editor for permanent id3 tags.
