Films from before 1927 should not be allowed to be classified as musicals
Currently, there are 200+ films from before the advent of sound listed as "musicals" on IMDb.
(See for yourselves: https://www.imdb.com/search/title/?release_date=,1927-10-05&genres=musical)
The Jazz Singer, generally considered the first 'talkie' and the first movie musical, was released on October 6, 1927. Now, I could understand it if I looked at IMDb and saw a few obscure experimental precursors to the musical being classified as such, but 206? I started trying to reclassify some of these as "music" (based on the plot), but stopped after realizing the sheer volume of them. Most of them have virtually no information online outside of IMDb, so it's virtually impossible to find out even basic plot details, much less view them and verify whether there's any sensical reason to call them "musicals".
IMDb has strict start and finish dates for the genre of film-noir (starting in 1927 and ending in 1958). Wouldn't it make sense to have a version of the same policy towards musicals? The idea that a silent film could be considered a musical is, to me, patently absurd. IMDb should make it a policy to automatically disallow any film released before The Jazz Singer to be classified as "musical".
P.S. The genres "music" and "musical" often get mixed up. While "musical" has a lot of genre conventions that depend on audiences being able to hear and listen to the music characters are directing at them, "music" is more based on theme. Thus, there's no reason that a silent film whose plot focuses on the life of a musician couldn't be classified as "music", considering that music would be a main theme. On the other hand, it is difficult to see how a silent film could contain "several scenes of characters bursting into song aimed at the viewer", which is what IMDb considers the essential requirement for a "musical".
