Hope you haven't gotten far. Don't use WMP.
It doesn't tag well with the S9. If you ripped to mp3, you can retag using something like the free program mp3tag. If you ripped to wma, I thing you'll have to re-rip.
On thing you could try is switching from MTP to MSC in your settings. If WMP will synch, you might have a chance. Media Player tends to like it better. It conforms to Microsoft's Zune Store Strategy. Ultimately, your working around a problem that only occurs with WMP, so, I tend to think you're better of starting over and cutting your losses.
