New music, Old music

[Spongebob]

Well yes. I overlap of late 70s and 80's music, and very little of early 90s music. But by the mid and late 90s I lost interest. I think that is always normal in every generation. 

I think this describes the situation pretty well.  The more music you listen to, the more you notice similarities in other music, repeated riffs, chord progressions, vocal styles and so on.  Every now and then I "discover" an artist that I had overlooked or discounted some time ago and then I wonder how I could have possibly missed this.  But its rare.  In truth, I don't believe there is an infinite range of musical ideas and it's possible that they will all be used up some day.

If there's one aspect of contemporary music that I appreciate, it's when a contemporary artist covers a song by an older act and alters the makeup of the song such that it sounds like a completely different song, yet I can still find the original in there somewhere.  That takes some effort.
