They have been for a while now. It started before the API thing with subreddits that were basically mirrors of English ones. But (badly) auto translated into German.
A few weeks ago, the Google results got flooded with auto translations. You can still find stuff that was written in German, but you have to limit the search to German subs (site:reddit.com/r/de, for example).
Or check the sub name in the search results. If it’s in German, you should be good. If it’s in English, or if it doesn’t show up at all, it’s usually a machine translation.
Yeah. Those keys on the piano are E and F. You can see those notes in the sheet music for the title track. Those long rows of notes are a bunch of E’s and F’s.
If you hit the play button in the bottom left corner, you can hear a computer-generated version of the song. Real version here.
