Alternative freedb sources


Can somebody provide a link where I can find alternative freedb sources to add to MP3Tag please?

I'm not sure if I read correctly somewhere else but is it possibly to add server into MP3Tag?

Any links welcome, thanks.

To repeat: The data quality of FreeDB is very low. Anyone can submit whatever he/she want. There is no data control at all.

Did you have a look at the web sources menu?
The standard installation comes with a musicbrainz script
