Merging Looney Tunes and Merrie Melodies
Perhaps the "Looney Tunes" and "Merrie Melodies" tags could be merged if possible? There's no significant differences between the series (same studio and artists) and it seems like it would only cause confusion. "Looney Tunes" is the better known title.

(Also the LT and MM titles were often swapped in reissues, so there's a good chance some classic Warner Bros. uploads are already wrong...)
