I'll be neutral on this matter because I've got an idea:
If we instead rename the actual page to "Streaming service" then split it in 3 parts: JDNOW, JDU2016 and JDU2017 (No acronyms of course). The JDNOW part would have every song before the arrival of Smile, the JDU2016 part would have a descrption saying that it includes all of the JDNOW tracklist and add a subtitle called JDU2016 exclusives which would have all the info. about the JDU2016 exclusive songs (ranging from Smile to the Stadium Flow FANMADE, including the date of release in JDNOW), doing the same with the JDU2017 part.
Just an idea to have more organized the wiki since the arrival of the streaming service.
