There are many ways to practise listening. http://dansbandskanalen.se/ = Here you can listen to typical Swedish schlagermusic. http://www.digitalasparet.se/ = This is a site where you can do many exercises and improve your Swedish. http://svenska.yle.fi/radio-vega = If you are interested in Finland Swedish that I speak, this is a place where you can listen to how it sounds like!

As for radio there's http://sverigesradio.se/ , as you can see it has various channels. P2 passes mostly classic and jazz, so you may like it, while P4 is more pop/rock oriented but also has various programs about Stockholm in general. In P1 they mostly talk, just yesterday I trying to listen to a quiz in it, for the rest I don't know but you can try it yourself. For tv series, there was a discussion just short ago in here in which various names of series were given, you can try to look it up.

Google "Sommar och vinter i P1" You will find a very nice radio program where swedes talk, one person at the time. Well prepared 45 minutes talk on any topic, from either a famous person, or an ordinary Swede with an interesting story. Google "Sommarvärdar 2016" to read more about it.
