Just more wanking with numbers. With that many tracks, no one
will ever hear a particular track more often than a few times a year
even if they are stupid enough to be playing music 24/7/365.25

And with them on a 256GB card in a smartphone, its MUCH
easier to specify what you want to listen to at a particular time
and can use bluetooth instead of farting around with that cable.
