> - Wikipedia still has the best common-sense/canonical info about singles. For example, Wikipedia will tell you in the first sentence (or infobox) "song X was first released on album Y in year Z." Answering that can actually be quite challenging on other services.
Sad fact: For a while Discogs had an experimental feature aptly called "Tracks". It allowed individual tracks, not just the whole release, to be viewed as separate entities along with references to all releases on which said track appeared. A database of canonical tracks.
It enabled me to see if that great track from an ultra-rare and hard to find album perhaps appeared on a compilation or any other much easier to buy release. Sure, you can achieve similar results by simply searching, but it's much more cumbersome and downright difficult when it comes to rather generic track titles leading to countless irrelevant results.
