Attached are registry settings to make "Enqueue in foobar2000" the default shell operation, without having to enable "Enqueue incoming files by default when adding from command line".

The problem I found with the latter was that with that enabled you cannot right click>play in foobar2000, as that would enqueue as well.

Disclaimer: you should always backup your registry before editing it. the attached registry file has been tested and works on my two machines.

edit: bah, didn't know there was a character limit to the topic description.
