I partially agree with the reasons of

But I would say from worst to best

>Korean
Popular media but it seems (at least to me) mostly limited to female-centric interests like pop music and fashion. Basically an inferior Japanese.

>German
Most Germans already speak English and didn't spread their language very far due to lack of colonies. Only reasons to learn are if you're a thirdie moving to Germany or if you like their history/literature. They are outpaced by other languages when it comes to media

>Russian
Unlocks Russia + some of eastern Europe and central Asia. One of most common languages on internet. I hear they have great novels and decent media.

>Chinese
Rising power who is starting to produce lots of media and useful for international business, but probably not that useful outside of Asia even when they reach their peak.

>French
Most international language besides English and also for traveling. Former lingua franca and probably the most useful language for if you get transported back to medieval or early modern Europe. Lots of media. Makes you seem more refined to normies and makes you a better English speaker

>Spanish
Safest choice. Unlocks most of LATAM. Lots of media. Easy for English speakers. Most useful in USA. Maybe some of LATAM will finally stop being a shithole.

>Japanese
SSS+ tier media. Lots of games, songs, anime, manga, etc. 3rd or 4th largest economy. Makes Chinese easier.
