"audio_playlist/1?destination=node" Access Denied

I reinstalled Drupal just to test this out, so everything is clean.

1) Download all latest dependent modules (token, getID3, etc)
2) Enable them, and then Audio's every component
3) Just to be sure I didn't miss out any permission setting, I checked EVERY permission setting there is.
4) Create Audio node - this works fine.
5) Go to Home, where it is now published.
6) Click on Add to Playlist, and I get a long message:

Access denied

7) Revisit every item under Administer to ensure I didn't miss any setting I should set.

There is nothing else I can configure, that might be related.

Does anyone else have this issue?
