You can configure how the lyrics are aligned in the lyrics panel.
Guayadeque allows you to save the lyrics embedded into the audio files and as text files in the folder you select, following the structure Artist/TrackName.lyric. With the 'Only for the selected tracks' option the lyrics will be saved only when you click on the save button from the lyrics panel.
Guayadeque searches first for already embedded lyrics, if there are no embedded lyrics it will then look for them on internet sites from the list of Sources.
