You can see the dropdown menu as the filelist itself, if you want for example to start playing the fifth song, then simply press the flash logo next to the fifth song. This goes for every other song aswell.
The RAWR-Player has a build in feature that calls the next song in the actual file list, aswell as an option to shuffle the current directory (playing a random song after the current one has finished playing).
If you want a different order, then just download the songs, store them on your hard-drive and use winamp for that. RAWR-Player was basically made to 'preview' a song before you download it from the 'File Server'. With this in mind, a queue feature will never exist. You are free to script it your self however, just look at how the virtual playlist is made and make some adjustments.
