Sad that this is true, though. It's "dated" not because mp3 format is dated, but because people no longer maintain their own music collection - outsourcing it instead to legit (e.g. Spotify) and illicit (e.g. YouTube) SaaS businesses. Which do not guarantee you that the song you bookmark today will be there the next year (as I myself experienced many times on both Spotify and YouTube) - but I guess songs get missing randomly and slowly enough that people don't notice.
