I'm looking for an application that automatically searches lyrics on the internet and stores them in ID3-tags. Such a program, called iArt, already exists for Microsoft Windows. Does a similar application exist for Ubuntu as well?
I know of no application that will actually automatically write the lyrics to the iD3 tag for the file but rhythymbox has a plugin that will download lyrics from the internet.
Also remember that not all lyrics are available and subject to copyright in many countries.
There are many applications that will however enable you to edit the iD3 tags of your files either individually or in a batch;
I wrote a python script that will search for lyrics and embed those lyrics to your mp3 files. Script Blog
