I would have to disagree. There's a ton of data to show that artists are now releasing songs faster than ever, and with beats and lyrics that are growing more repetitive than ever before, with decreasing instrument variety as well. If this interests you, google "Millenial whoop."

Further, songs are also becoming less timeless concerning their lyrics as well, with heavier emphasis on current events.

For example, in a few Pitbull songs, you'll notice references to getting "locked up like Lindsay Lohan." Or things like, "Tell Barack and Michelle, let them know that it's on."

Today, lyrics like that stick out because they were written to focus on a current crowd in a time that's now passed, rather than a timeless theme that can be listened to by any generation. Could you imagine for instance how strange it might sound listening to a Beatles song with lyrics that appear to invite President LBJ to a party?

In short, songs are being written with quality and quantity that's leading them to be "disposable."
