HDtracks is the premiere online music store for audiophiles who demand the best sounding music. As consumers are left with few options to purchase high quality recordings, HDtracks was founded to fill the void. It is our purpose to allow our customers access to the largest online library of DRM-free CD and DVD-Audio quality downloads complete with liner notes in a PDF format.

We believe a great recording is not only the tracks of sound, but also the creative collaboration of composers, producers, musicians, recording engineers, annotation writers, and visual artists. We feel strongly that not only everyone involved in the creative process is recognized for their work, but that music consumers be able to learn about the people involved in the production of the music and therefore participate in a deeper understanding of the music. HDtracks provides audiophiles who demand the highest quality recordings with an online experience not available anywhere else.
