Good call on the Mark Knopfler disc. All of his are well-recorded, as are the later Dire Straits albums.
If you like 1980s synth Rush, then try 1985's "Power Windows". It was their first all-digital recording.
I find the vocals and solo piano on Coldplay's "Parachutes" and "A Rush of Blood to the Head" to be very pleasing.
If you haven't already, you may want to open up a whole new can of worms and get some DVD-Audio and/or SACD albums. The REM DVD-As are very good.
P.S. Dan, increase your medication! I'll PM you the directions
