You can embed the lyric contents into files or into tags.

Neutron will check for ti, al, ar tags in every found txt/lrc file found inside the music folder. If filename does not match any music file then these tags are used to guess the relation of the lyrics. Neutron had issue with leading/trailing spaces in ti, al, ar tags which break this guessing but since next update it will be fixed. You will need to long press on source entry and do full rescanning by using SCAN button.
