Buc it's easy to get spotify and there's lifetimes of music on there, you can use/try it for free on your laptop (you have to put up with odd ad) - here's the registration page for the webplayer - just double check you are signing up for free version to check you like it ie don't give any bank details (not meaning to be patronising, it's just easy to fill these things without any thought)

Or maybe get some of your family to do it & put the app on your laptop or phone?
Just checked, there are loads of disco playlists. You'd be in heaven
