Has acceptable and desired song length changed?
I remember being told that optimally, a song should be no more than 3 to 3.5 minutes long. Listening to Pandora today, many of the songs were between 4.5 and 5.5 minutes long. Has the goalpost for song length changed, or is the 3 to 3.5 minute range still optimal? I do of course realize there have been many well known songs that are well over that length. I'm just wondering if the thinking is still the same, or if that thinking has changed with new listening options (streaming, etc.)?
