I like to be able to sing along to songs when I’m alone in the car, so even if I don’t understand the meaning of the words, I like to know the words.
I also enjoy word play, and Du Hast has some of that. So knowing the bit of trivia about ‘Hast’ and ‘Hasst’ being homophones in German and meaning ‘have’ and ‘hate’ respectively, and the main portion of the lyrics being wedding vows adds a layer of enjoyment to the song for me.
Personally, I don’t like the idea of any recommendation or advertising algorithm using personal information of any kind. Though I can understand why location would be needed for advertising: in order to ensure ads for regional services are not shown outside of that region.
The kinds of data that I think should be used:
-Recommendations:
-Like history
-Watch (or view) history - specifically (and only) if I click on a post or watch more than some reasonable percentage of a video that would indicate I watched the entirety of the video.
-Advertisements:
-Location (based solely on IP)
-The content currently being viewed, based on a general categorization of the content. If I’m watching a video about technology I don’t need to be seeing ads for financial services.
