You need to have a CD player to use this book. I wrote to the publisher about getting online access to the MP3 and they replied, "Hello and thank you for your letter. I'm sorry to hear you can't access the audio material of "Naljaga pooleks", but unfortunately we don't have a quick solution to your problem as there is no online version of the audio. This book was first published in 2006 when CD-s were widely used and we've been doing the reprints due to market demands. Sorry for the technology cap! Will consider it when and if we do the next print." Basically, they said tough luck and better luck next time. So sad.
