I just like a great song, sung by a good or better singer, played by a good or better band. Is that too much to ask? ;-)
In the first cubicle of my LP racks are albums by Curtiss A, ABBA, AC/DC, Roy Acuff, Arthur Alexander, Mose Allison, The Alpha Band (T Bone Burnett, David Mansfield, and Steven Soles), Dave & Phil Alvin, Al Anderson (pre- and post-NRBQ), The Animals (before Eric Burton became psychedelicized), Joan Armatrading, Asylum Choir (Marc Benno and Leon Russell), and Mike Auldridge (master dobro player).
Then there are my CD racks.
