Take the stuff you listen, but a good example and a nice benchmark would be Katie Melua's "Nine Million Bicycles" CD single. Cleanest production I've heard in years - instruments are nicely placed in the mix, good clean bass, three tracks (Guernica and the classic Stardust which she does an okay job on in addition to the title track). Get it off Amazon for next to no cash probably and I never fail to try this one out along with all the usual Yes and Genesis stuff I take for these things!
