* It's a mutant MP3 that decodes as 2ch but output can be routed to 6ch somehow, if manually
* activated. Fraunhofer IIS's MP3sPlayer can do it, as can PS3 (fw v2.40+) but no others seems to.
* So simply play as 2ch, they sound ok with slightly wider feel. No XVAG/MP3 flag exists to detect,
* can be found in v0x60 (without layers/subsongs) and v0x61 (with them set as 1) */
