I have just the thing kind of in both ways one might look at the concept. Both "new to me" as is the official intent and a newer version of an old thing.
Here is a cover of Kokoro -- a relatively "old" Vocaloid song covered by #Hanatan but a newer redone one better than the first she did that I recently came across: https://www.youtube.com/watch?v=pYpDJkih94Y
Plus just plain a darned nice song anyway.
Still a pretty "old" song, so many may have never heard it.
