hwkiller [1] filed a deletion request for rhythmbox-radio-browser-git [2]:

Incorrect name. I meant to submit this with the name "rhythmbox-plugin-radio-browser-git", as there already exists a "rhythmbox-radio-browser-git" in the old aur. The two packages target different radio browsers, and are not duplicates.
