You've submitted more apps to the store than I realised. Good Job. (for someone with no graphic design skills )
Hopefully you can update some of those to Windows Phone 8 apps pretty soon, especially the musical ones. There must be something important in the SDK that they don't want to show off before the official launch of the newest hardware. At least I hope there is.
Yes, hoping that timing won't be as much of an issue as it is in wp7 for music related apps.
