You can listen to a vast, vast, vast (VAST!) amount of music, for free if you use the regular service, without the need for radio presenters diatribe.
If I work from home, which I sometimes do, or if I'm hanging at the house and want music on I will always use spotify over putting the radio on.
I've created myself a gigantic shuffle playlist with hundreds of my favourite albums (plus some new stuff I want to check out) and it is magnificent.
