Somehow you have changed the default player for mp3 fom iTunes to WMP. You need to change it back again .
Right click on one of your mp3s select open with ...choose iTunes .. It will ask, I think, do you want to use this for all files of this type. Say yes. and all should be well.
I've guessed at the exact procedure as I use Mac.. but it's pretty much as I've said.
