What about people that are technically good at performing music, but can't write an original song to save their life? I think that's what people mean when they say band XYZ sucks. Of course they aren't bad at actually performing the music because then as you said they wouldn't be able to make a record. Just because they play a song well doesn't mean it's good, though. It could be totally derivative of another band, or have insipid, meaningless lyrics.
Hm... That's an interesting point. The songwriting quality definitely plays a role.
However, as a counterexample, think about how many people liked Britney Spears when she was in her prime. How about N*SYNC, or the Backstreet Boys? A lot of their songs, arguably, had VERY stupid lyrics and were extremely derivative. Still, their music was very popular at one point.
Granted, their popularity may have been more due to the band members being good eye-candy rather than due to the merits of the music, but when/if you say they were 'lousy bands' it's still because you, personally, did not like them.
