I'll take your word for it re ST.
That Burt/Elvis record, I bet, will sound great 20 years and more from now, but I bet we won't feel the same about many of today's "modern" records.
I work in tv/film (three emmys) and write and produce everything from the most dense orchestral, current loopy techno (and all the sub categories that entails these days) and simple underscore for dramatic shows. So, yeah, I'm fully aware of all the modern techniques. For me, it's more about keeping my piano in tune and my guitars maintained.
Full disclosure: I use everything available to me on my PT HD accel rig

However, I don't have the time to give in to massive tweaking. Even if I did, my musical training would stop me short along the way and say "let's get a better player or write a better (perhaps simpler) part".
However, I love cutting sections, moving them around, turning sounds from my acoustic piano into gothic horror drones ( Bruno Reso's pretty neat) building my own drum/perc loops ,etc. in short, anything I can think of.
I'll also spend many off hours programming the best synth engine ever made, the Kurzweil K series.
I've got a tough one this weekend, though, I've got to write a "modern" piece in the style of a mid 50's romantic comedy for broadcast immediately. Arghhhhh....
