Music Player that plays WMA Files on 4.2.1. Jelly Bean- Samsung galaxy si9000

Hi there.

I'm looking for an update date jelly bean ROM for my Galaxy S I9000 which has a good music player that is

capable of playing WMA files!?

At present I'm using Slim bean 4.2.1 v1.0 on Samsung Galaxy S i9000 phone.

Obviously the Stock Samsung Music player was brilliant on GB.

Ideally I want the stock Samsung player back? But it wont work due to lack of touchwiz on the present custom ROM.

Some one suggested ..."to be able to play WMA you can modify build.prop."

How do you modify this?

Any ideas?

Thanks
