After poking around for a while on HDtracks.com I decided to buy an album in 96kHz/24-bit FLAC format. It sounds most excellent on my PC but will not play on my Galaxy S4. I later found out that, while Android natively supports FLAC, apparently
it only supports up to 48kHz/24-bit files. I've tried a handful of third-party media players with no luck. It's not a huge deal; I'm just curious to know if there's any way to play the original files without converting or downsampling them.
