have you ever noticed how many people are involved in the making of a cd these days, and how clear the sounds are?
of course there are artists who use sampling cds without even changing the sound, artists who remake - not arrange - songs just old enough to be out of the reach of teenagers' memories, not to mention artists who rip off, repeat, regurgitate just to make money.
but that's not new! heavens above, artists, musicians and writers have been borrowing for ever.
we don't live in the two guitars, bass and drums era anymore. sound is filtered through computers, mixers the size of football fields, corrected, effected, tuned, detuned etc etc etc.
teenagers have terrific taste. i believed my own taste at that age, and i believe the taste of teenagers today.

p.s. sampling is also "quoting" and often brings a beautiful but forgotten phrase back to public attention.
