I was reading webuser and saw a mini workshop that showed a great tip to stream music from a massive collection online.
Basically you go to the start screen and put the name of an artist in and then select it when it comes up as a result. This then opens wikipedia and lists loads of music and video links in connection with Xbox music.
I tried this on my laptop and it worked a dream but when I tried it on my desktop all that happened is it gave all the music I had on my computer for the artist I had entered but didn't activate wikipedia or xbox music.
I have both these apps on my desktop.
Does anyone have any ideas?

I have windows 8.1 with Media Center on both computers
