Cause I don't use the beta I can't test it. I can only repeat myself as posted at FolderSync:

Cause I don't use 1.2b1 I can't test it.
If you want to try it:
Download the xpi (for example here v1.2.0.0) and change in it with an archive program (for example 7zip) the file install.rdf:

Find the following:

    <em:targetapplication>
      <description>
        <em:id>songbird@songbirdnest.com</em:id>
        <em:minversion>1.1.1</em:minversion>
        <em:maxversion>1.2.0a</em:maxversion>
      </description>
    </em:targetapplication>

and change it to (bold=changes)

    <em:targetapplication>
      <description>
        <em:id>songbird@songbirdnest.com</em:id>
        <em:minversion>1.1.1</em:minversion>
        <em:maxversion>1.2</em:maxversion>
      </description>
    </em:targetapplication>

So the Add-On will be accepted from Songbirds up to Version 1.2.
Now you install the xpi and hope that it works.
Good luck! (Hope you don't need it) ;)

@klint:
the verson bump is out, so it should work regularly with 1.2.0.
