Not on my iPad no, I loaded a handful of songs just to see how the cloud worked but that's about it. Most of my listening is still done on my old iPod nano, I love that it's so small and can be carried everywhere. Also as its quite an old piece of tech I don't worry about losing or damaging it. That said I see no reason to upgrade it just at present, that may change if I get myself an iPhone at a later stage (I'm using a BB at present, supplied through my job and have little reason for a second phone).
