Recomended WMP remote app for i5 phone

I know this has probaply been asked befor but I am just starting to experiment with computer audio. I have ripped a couple dozen CD's to Windows Media Player (Toshiba laptop with xp to usb dac) and I am looking for a good app to use my iphone 5 as a remote. I realize there are other set ups better than WMP but this is mainly for background music as I work. Please be patient I am an old dog trying to learn some new tricks.Can anyone recomend a good app?
