Funny you bring this up, I was just talking to a friend about this very thing, and how in my opinion music has suffered for it.
I started playing in 1966 at age 14. I'm from a small town in north central Texas, and this is what is was like for my little band to learn a new song.
First of all we had to learn about the music. There was no FM radio yet so all we had were am stations from Dallas and Wichita Falls, and we weren't a top 40 pop band. So we had to read. Hullabaloo magazine, which turned into Circus magazine around 1969 or so, was my main source.
Anyway after you'd read about the music then you had to find the music. The closest record stores were in Wichita Falls almost 50 miles away, so it was a day trip to drive to Wichita Falls, hit the record stores for the vinyl, hit the music stores for strings, and drive back home.
Now you've got the music, but to learn a song you probably had no way to record it. Cassette wasn't around yet and eight-track recorders were very rare, so that meant sitting at the turntable and lifting the tone arm over and over and over again, for hours, as you figured out the licks by ear.
So you've learned the music, now you've got to get the freaking lyrics. That means everyone sitting around the turntable and playing the song multiple times while everyone writes down what they think the lyrics are, then comparing notes and eventually compiling what everyone thinks is right.
So what all of that meant was it took a HUGE commitment. It was nothing you did casually, and just in my mind we appreciated and were deeper into the music because we had to work so freaking hard to get it.
I don't need to tell you that by comparison today you've got about a hundred ways for music to be delivered to you, then you go on youtube and there's a guy showing you how to play the song as the lyrics scroll by. Yeah that's convenient but in my opinion you're missing a lot. Mainly doing it the old way you accidentally figured out other licks and inversions as you're trying to learn the song you're working on. Consequently by the time we were 15 my little trio could improvise for hours.
In 1969 my parents bought a console stereo for Christmas with an FM radio and a reel-to-reel tape recorder in it. Just a few months before KFAD and KNUS, the first underground FM rock stations in Dallas had cranked up, and we were right on the fringe where we could pick them up and record. THAT was an epiphany.
