Why do you want amarok packed with LMMS. I also doubt that would be legal.

You lost me there. amarok is to play music files.
Files you can import into lmms. ,mp3 .wav .ogg and so on.

Me personal don't like amarok at all. That's why I am using QMMP with a Winamp skin to listen to music and my own tracks produced with LMMS.

For windows users reading this post and missing Winamp , QMMP also has a Windows version.

I don't think amarok has a windows version.

LMMS started as Linux only, but is since many years cross platform.
