Can't I listen any kind of music by 7th percept? Nacca gīta vādita visukadassanā
mālā gandha vilepana dhārana
mandana vibhūsanaṭṭhānā veramaṇi
sikkhāpadaṃ samādhiyāmi.


I undertake the precept to refrain from dancing, singing, music, going to see entertainments, wearing garlands, using perfumes, and beautifying the body with cosmetics
nacca - plays/dances
gīta - song
vādita - music
visukadassanā - visiting shows


So yes, it includes all music. Even if you hear a song by chance and you indulge in it, you break the precept.
