Change
In addition to many changes in specific sounds and technologies used, there has been a shift in the content and key elements of popular music since the 1960s. One major change is that popular music has gotten slower; the average BPM of popular songs from the 1960s was 116, while the average of the 2000s was 100BMP. Additionally, songs getting radio play in the 1960s were, on average, only about three minutes long. In contrast, most of the songs in the Billboard Top 5 in 2018 were between 3:21 and 3:40 minutes long. There has also been a drop in the use of major keys and a rise in the use of minor keys since the 1960s; 85% of songs were in a major key in that decade, while only around 40% of songs are in a major key now. The subject matter and lyrics of popular music have also undergone major change, becoming sadder as well as more antisocial and self-centered since the 1960s. There has also been an increasing trend of songs' emotional content and tempo not following common associations; for example, fast songs with sad subject matters or slow songs with happier content.

There are multiple possible explanations for many of these changes. One reason for the brevity of songs in the past was the physical capability of records. Vinyl record singles, which were heavily favored for radio play, only had room for about three minutes of music, physically limiting the possible length of popular songs. With the invention of CDs in 1982, and more recently with streaming, music can be as long or short as both writers and listeners wish. However, songs have gotten shorter again, partially due to the ubiquity of streaming. The average song length in 2018 was 3 minutes and 30 seconds, 20 seconds shorter than the average in 2014. The most probable cause of this is that artists are now paid per individual stream, and longer songs could mean fewer streams. As for the difference in songs' subject matter and emotional content, popular music since the late 1960s has increasingly been used to promote social change and political agendas. Artists since that time have often focused their music on current events and subjects relevant to the current generations.
