With storage being cheap, why not just download FLAC? And with streaming being easy, why download at all?

The case for M4A in 2025:
HDtracks primarily pushes high-cost FLAC, but they have recently introduced a "Portable AAC" tier. This gives you a 256kbps M4A file for roughly half the price of the FLAC version. With storage being cheap, why not just download FLAC
To understand the demand, it is necessary to understand the file specifications: HDtracks primarily pushes high-cost FLAC, but they have
Why 256 kbps? When Apple launched iTunes Plus in 2007 (originally 128kbps AAC, upgraded to 256kbps in 2009), they commissioned listening tests. The results showed that most listeners could not distinguish a 256kbps AAC file from a lossless CD source (1411kbps WAV) in blind A/B testing.
Compared to a 320kbps MP3, a 256kbps AAC M4A is more efficient. It retains more high-frequency detail (cymbals, air, harmonics) while being approximately 20-30% smaller in file size. For mobile devices, this means saving gigabytes of storage without sacrificing fidelity.
