Cannot perform Type Migration

I am unable to perform the Type Migration int he Refactoring video. I receive the error below when I change the Song class to SongRequest in the Migrate type to field:

'java.util.Queue<com.teamtreehouse.model.SongRequest>' is an invalid type'

Any thoughts? This piece right here is inhibiting me from completing the code challenge that follows.

To work around this you need to position a caret (^) on type of field, variable, method or method parameter to be refactored. I did this and it worked for me.
