LED RGB AL RITMO DE LA MÚSICA

Tengo que hacer que una tira de LED RGB se iluminen al ritmo de las canciones que salen por un altavoz. Pero son varias canciones, por lo que tenemos sus codigos pero por separados. Como puedo unirlos?
Y como puedo hacer que la tira RGB vaya al ritmo de esas canciones? Por favor ayuda!
