romkoDid a little math (aaah!) and I think I've worked out where this comes from. If you calculate for FLAC files at 1141kbps across the expansion slot's maximum 256GB card, then you can, in fact, fit about 6400 songs at a very loose average of 4min30s per song. Very inaccurate and misleading to present the numbers this way; but I'm pretty sure that's what is going on. For those interested, the same 4min30s songs on the original 8GB would be about 200 songs - but this doesn't account for storage lost to formatting/os/etc. so it's probably not a bad idea to estimate less (maybe 150?). Hope that helps!
