question regarding music player in Xoom

[STEMALO]

It seems my music library doesn't show what I actually have in the music directory. I can't seem to be able to find any settings. If I delete some music it still appears (but doesn't play). Also, even if I rename the albumart file sometimes I see the picture and sometimes I don't.
Your help is creatly appreciated.

What do you mean by this? I converted all of my music onto the Tablet and had to download Pulse to use it. Most is not in MP3 Format. I like there App for Music they have on this and how it shows the album art and everything. But its just not working right so I downloaded an app from the market that will play ALL of my files.
