Cambridge Academic English B2 Upper Intermediate Class Audio CD: An Integrated Skills Course for EAP (Cambridge Academic English Course)

Guys, I understand that the book was designed some time ago, but there's not even an MP3 or other digital format? No one uses CDs anymore, let alone anyone in universities to teach listening skills. CDs and DVDs? Why would your team not have simply recorded the audios and sold them as digital versions? Multiple books from Cambridge come with audio that is either free or at least digital. Kinda beyond the year 1995, thanks. This literally ruins your entire series, by the way. If people don't have a CD player... they can't use the book for listening? WAKE UP!
