Hm. The output in the serial monitor isn’t consistent. Here’s a list of the errors:

So sometimes it cats two lines together, sometimes it appends a stray character to the end, and sometimes it does both. The second line above is really weird because that looks like a valid filename. I don’t know why that instance didn’t work.
Adding current_track_[0] = [0] to the constructor results in a compile error:
