When Does Music Get Old or Outdated?

I'd say that it becomes dated when a new trend comes along that renders it outdated. It could be outdated in a bad or a good way. Early funk and disco became dated in a relatively good way because they could afford a whole orchestra whereas later groups had to make due with smaller bands. Obviously funk ended up better off than disco after it got banned but that's a slightly different topic. Rock and roll, literal rock and roll, became outdated because it was surpassed by later rock music that took it in a more sophisticated direction. I'd say that music becomes outdated once its ideas become part of a larger culture and that can happen fairly quickly. Most music is mainstream fodder within 5 years and outdated soon after.

Good music never gets old or outdated.

Never, never, never I say. Especially since music is as dead as dead

Ask Beethoven and Tchaikovsky if their music is still relevant.

Well a scene/genre/music tend burns out after 5 years or so (by that I mean all the big bands name bands from that scene break up, move on to a different sound, or become irrelevant and the overall fanbase diminishes greatly) and then usually another 5 years after that for people to look back and think "What the fuck were we thinking?" (ie "outdated"). Nu-metal is the ultimate example of this, the genre blew up in the late 90s, by the mid 2000s or so the genre was dying though there were still (unfortunately) some big acts still selling quite well (Korn, Limp Bizkit) and by the 2010s the genre was seen as something incredibly lame and a regretable relic of the late 90s (that Limp Bizkit joke in Deadpool comes to mind).

Some music just goes on hiatus for a while. A lot of seemingly outdated music rises from the dead. When we Boomers are dead and gone our music will survive or be revived. Our kids will pass it to our grandkids, etc

I still play 1930s stuff.

Gonna have a slightly , long-winded blurb here.
A year or so ago, my girlfriend said to me "Are we getting old".
This was related to the current chart ' music' we were subjected to over the speakers at our office job.

Girls with heavy colds mouthing to audiotech voice thingys and guy's pretending to be nasal plastic Jamaicans ranting  stylee about youth angst and/or sh!te.

I said NO.
My rationale encompassed the fact that 9O% of the the youngsters at work ( post teens and mid to late 2o's) were pleading for 80's radio stations as they detested the knock-out current phlumpf  crap.

Then the offer came up to check out via Internet ANY week in the 8O's top twenty singles charts and how many songs folk still knew.
Whichever week was checked out....nearly all and sundry  knew and grooved to 90% of those songs.

Whereas the general consensus was that the current chart stuff would not be be recognised in 8 months time.

There are at least 20 or so current acts that I personally think are brilliant at the moment.....but the singles charts and pushed shite on the radio is knockout and throwaway  phlumpf.

Good music never dates....and N0, we are Not getting old.

End of long waffle.

Music only becomes 'outdated' in the ear of the listener. Otherwise the term has no relevance per se, as far as music goes.
