Sorry, Brain malfunction, i had intended to say usb flash based players,
particularly those that are flash storage based without internal DBs.

See, these player's capacitys usually range from 32Mb to 1Gb. They are
used mostly for taking a _selection_ of music from your normal
collection out with you.

I like this scenario for the large HD based players that act as a music
repository. However (and this is probably just a specialisation of the
above scenario) I am aiming to support the millions of cheap flash based
mp3 players. HDD players should behave differently, as they are an
identifiable collection of music. Usually because of the sheer number of
songs available on such a device, some form of database searching or
sorting is required.

Flash based players are used differently. They are used to take some
selection of a collection of music portably with you. I don't need 8
days of music if i'm only listening to it on the train in the morning.
In that case, i'm probably only going to need a CD or two worth of music
from my collection, and the selection is probably going to change daily.
