In the desktop version of CLZ Music, it is possible to add and/or link digital music files
is this also possible in the WEB version?
It is not possible to link to local files on your computer.
And: It would be (security wise) really bad and probably blocked by your browser to let a website search for files on your local computer (can you imagine)
You can add web-links to files, say you grab a link to Spotify or Apple Music for that album, and put it in the Links section of your music album (in the edit album screen) - that could link you directly to the album like that.
