Music Fanart wont change ?

I have lo res fanart on a music artist and trying to change to hi res. Tried few things:
1. Changed the fanart.jpg inside the actual folder where the artist and album reside
2. Added fanart.jpg (new hi res) inside the album folder as well as the artist folder.

eg: Artist fanart.jpg
Album 1 fanart.jpg
Album 2 fanart.jpg

3. Navigate to Music, Album (or Artist) on main menu, highlight the album (or Artist) hit "C" and album information (or...) then go to Get Fanart - browse to the hi res fanart and hit ok

(hi res and low res pictures are different pictures so i can ensure i am actually changing them)

I dont know the architecture of xbmc but one time i had a similar issue with extrafanart in movies and i was directed to delete (rename original first) textures.db - i tried this also.

4. I also deleted entire music library, and re-added it.

Where is this darn fanart hiding?

Love XBMC and all you folks developing a knock out product!!!

Many thanks in advance ...
