CCR's good, too, IMO. EVERY album is worth buying,
(maybe not the later greatest hits shit). A lot of band's
greatest songs you'll never hear on the radio, IMO, or
find on a "greatest hits" album/CD. You will NEVER
hear Pink Floyd's "Echos" on the radio, for instance,
unless you request it, at 4:00 am

. It's one of
my favorite Floyd songs, but it's too long for
"commercial radio".
