Care to elaborate? To me, it seems AIMP
devs are using Sourceforge
services for filehosting or alternative download location. According to the licenses at http://www.aimp.ru/index.php?do=eula
appears to be closed source freeware -- but this has been done before...
SourceForge is only for open source applications. The project page for AIMP lists it as AGPL (which it is not). AIMP is closed source and hosting it on SourceForge is a violation of their terms of service. I've filed a ticket to have it taken down.
