I just want an mp3 player to replace my Walkman with sensme, they killed sensme and nothing has replaced it so to date the best mp3 player I own is that little thing, I tell it what mood I am in and it always delivers, I dread the day it dies.
I've tried cloud based music services like Spotify etc they are not really same thing as it's just global playlists for a mood/genre, not something tailored to your tastes in a set catalogue.
