With .mp3's dominating the portable music market, many people forget that, despite their popularity they are far inferior to the other choices out there. AIFF, ALAC, WAV and FLAC files offer superior, lossless, high-resolution sound that .mp3's simply can't match.
At HDtracks you can purchase 1:1 copies of the original master audio recordings of your favorite artists, so that nothing gets lost in the translation. Think of an .mp3 as a 480p SD DVD and an HDtrack as a 1080p HD Blu-ray, about double the quality. The difference is that big.
HDtracks can be played at home or on portable hi res audio player. With a huge selection of music to choose from (Deep Purple to Daft Punk) HDtracks caters to the discerning audiphile who wants only the best available source files for their music.
