Is that relevant? Usually it’s just a clip- but the option to find the song and hear the whole thing is always there, if you care enough.

One impact social media has had that is fairly new is the song made for social media. What I mean is songs that have maybe as much as 40 seconds of actual song. Regardless of how long the full thing is, you’ll have heard everything the song has to give you in less than a minute. There’s a lot more of that these days. But that’s not really what you asked in the first place.
