Local music not listed

[user-removed]

Servus,

i updated a few songs to my playlist, but spotify is importing the songs i got on my pc to the playlist instead of the spotify arsenal or whatever.

So, friends are listening to my playlist but cant listen to the songs which are imported from my local pc.

Heres the question:

How can i upload the songs which are on my pc or disable it, so my friends can listen to all the songs in my playlist?

PS:
Thats my Playlist:
http://open.spotify.com/user/1127145693/playlist/5toLgdFagkxwN9kPdbhwQb
spotify:user:1127145693:playl...

For example i got  "Whiskey in the Jar - Metallica" in my PL but my friends cant listen to it, cause its from my local pc.
