You dont get Music, Films and TV programmes, with just Prime, you have to have to buy the Fire-stick.
I have Prime because I, and all the family, near and far, use it, so it save us all money on postage, and any seller disputes are dealt with straight away.
As for the films etc, not that impressed, as you have to pay for some of them, although some TV Iplayers is free.
If you haven't seen 'The Grand Tour' the stick was worth it :-)
