3 column layout for a song site. Sidebar on left/right, and content between them

So I'm working on a website, an anime one to be precise, where people can read about anime songs, their singers, rate them/post comments to them, add them to their list etc., and this is the current layout of the site of a song.

I think it's decent, and I'm planning to keep it this way, but I'd like to know what others, maybe some experts think about this layout.

So as you can see, on desktop view there is a sidebar menu on the left(which can't be closed), and there is another one on the right, which contains some info about the song, such as the embedded youtube video, some statistics, info about the singer(if exists),anime, and the lyrics at the bottom. Both sidebars and the div between them are separately scrollable, but the scrollbars are hidden, because IMO it would ruin the design/layout.

And between them the content div is placed, which contains further information about the song(statistics, song recommendations, comment section etc).

Their width goes like this: 20-65-15

On mobile view, the sidebar on the right is being pushed to the top of the content div, since it perfectly fits in the screen size of a phone, and of course the menu(but without the search section) can be opened with the usual hamburger menu icon, but unlike most sites, it's placed on the bottom.

This layout is also convenient when the user wishes to read all the comments. On that site, the layout is still the same, so the sidebar on the right is still visible. But this time it's only visible on desktop view, so this is one privilege of those who visit the site on a PC.

Site of all comments

Do you think a layout like this would be convinent for the users? Or isn't it too unusual to have sidebars on both sides?
