Except the Materials Usage License update states otherwise:

"In relation to any functions within the game which allow you to perform virtual musical instruments (“performance actions”), you are strictly prohibited from performing the music of any third parties. You hereby warrant that your performance using the performance actions will not infringe the rights of any third parties and you shall indemnify us in respect of any breach of such warranty."

It then goes on to discuss uploading and recording, but this is specifically stating that its prohibited to even perform third party songs whatsoever.
