Lama Zopa Rinpoche asked for the recording of the lung to be made available for anyone to listen to while walking, driving a car, etc., playing it loud so that animals and others can hear it and thereby benefit from it as well.
Rinpoche recorded the Manjushri-nama-samgiti commentary and lung, along with a variety of other prayers, in August 2006. These recordings can be listened to on the FPMT website. You can find links to this practice in the FPMT Catalogue.
A transcript of these teachings is forthcoming.
