Another part of the shift might be time as we grow older. I remember getting a new cassette or cd as a teenager and sitting down with headphones and the lyrics. And I would listen to the album.
This.
I very much miss my younger years when I had time to sit and listen to a new album over and over, often with headphones, always while having the lyrics open in front of me. Lack of money to buy much also made me much more selective in purchasing.
This is 100% of why I can still recite the lyrics to nearly every Rush song, Dream Theater song, and many many others prior to about 1999 or so. After around that time, life started getting too busy, and I just haven't had much time to do that since (significant pay increases also allowed more impulse buys).
An album has to *REALLY* grab me at this point musically in order for me to set aside that time anymore. Seventh Wonder is one of the few "new" (to me) bands of the last 10 years to have inspired taking that time to really
listen the way I used to do regularly.
And for me, at least, my favorite, most-listened CDs tend to be the ones with great lyrics with the music...if I don't have time to learn the lyrics, it'll probably never make it to be a "top 20 favorite" CD.
The sheer quantity of releases (and purchases) is also an issue. I know can't compare to some here, but with just my collection of over 1500 store-bought CDs (plus all my (legal) downloads), I have -- literally -- 82.8 DAYS of music in my collection, according to iTunes' tally. That's nearly 3 months of 24x7 listening, with no repeats and no breaks.
I know that I own dozens and dozens of CDs to which I've never, ever listened. ProgPower is actually to blame for a lot of them. I haven't bought many in recent years (due to having too many unlistened), but for the first 10 or so ProgPowers, I'd come home with 20 or 30 CDs, every year. I'd listen to the ones I was most excited about first, of course....and never even get to the rest of them.
I actually keep a playlist called "UNLISTENED", and anytime I buy new CDs, I try to remember to throw them in that playlist. Periodically I review it and see what no longer qualifies to be in there (because I've listened!) and remove it. Also, occasionally I'll simply put the "UNLISTENED" playlist on, or pick a CD or two from it.
It helps, at least...
First world problems, eh?
