every song regardless of whether it was a hit or not? the b sides and the fillers on albums?
for me, that’s the doors.
absolutely love every single song they ever put out. know all of them verbatim, too. even after not hearing most of them for quite a while, i still sang along with every one (not missing a word or a beat, either) when i went to see ’21st century doors’ a few years ago.
led zeppelin i like about 95% of their stuff, same for genesis, phil collins, chicago, blue oyster cult and, gee, a host of others.
the beatles? no, i don’t like every single song…i like only about 80-85%.
do instrumentals count? kenny g is excellent – although not really my ‘style’ of music, i do like the sax and he’s an excellent musician.
