This store, which we are using for our order fulfillment, in my opinion unwisely calls regular CD quality files ‘HD’. I suppose they are in relation to mp3s! ;) But it is certainly not the kind of high resolution audio format we are discussing over on the audio demos page. The store shows song prices with a little HD in a box beside them. Unfortunately, we can’t hide that little box. That certainly would clear up any confusion. Just keep in mind, their ‘HD’ tag just means normal CD quality.
So, to help clarify for you which product is which, all davidlevyscoring High Resolution audio albums have the following ‘Hi-Res AUDIO’ logo directly on the store album cover. Hope that helps.
