I understand music mod isn’t a massively used app. but it looks fantastic! and you can make it look however you want pretty easily. i have edited the .apk file so you can install this version straight over the top of the one you have. Like most of the other themes people have made for music mod, this uses the 4×3 widget.
here’s my theme for it anyway…
there are matching picture frame widgets on the way (obviously) lol
here’s the download link for the MusicMod: http://www.megaupload.com/?d=XTDUOJLH
to install, select the .apk file you have just downloaded and it should ask you to install it straight away.
