If you want OSD, try osdlyrics.
To get a list of high-rating music, try (assuming the path name doesn’t contain the symbol |):
sqlite3 ./sticker.sql 'select * from sticker where value >= 4;' | cut -d '|' -f 2 > ./list
As soon as you have the file list, you can do more things like putting those songs in a separate folder (Here I use tar to keep folder structure):
tar -cvf - -T list | tar -C <dst-folder> --strip-components=<strip-depth> -xvf -
strip-depth depends on the database path.
