The save button neither works in the web-version nor on the Linux client or Android client for some bands. Examples would be CKY, Deftones and Otep. For others it seems to work just fine.
Now, the save button does actually save the album, but only on that client and for that session. Close the client, the save is gone. I've read about someone suggesting to create a playlist with the buggy songs, then saving the albums again and removing the playlist. No such luck, same behavior as already described.
Any help is appreciated :)
