This is sad news. I did read about some time ago but kind of was hoping that it was not true.
Have not checked out why they are doing this but in either case it is not good.
It was one way to get exposure for tracks to people that are using the same apps plus to be able to hear what is possible to do with the apps. Maybe the best critique of apps there was!
SunVox will have one page open but it is not as convenient as there need to be sent a message beforehand and it is a private person holding it meaning that if he gets bored the page will die out... (If you read this purelygrey do not take it personally, maybe you keep at it for years to come!). In either case to post SunVox tracks go here:

If you are a developer of apps and have a page for sharing music on Soundcloud or other page please contact me at: musicalandroid@yahoo.com and I will post it.
