There are waaaay too many bands that could fall into the 'worst band ever' but my pick has to be either Styx or Kansas. Granted, each band has had a track or two that was good but if you stack the majority of their work up end to end, it would be a tower of sh*t that could block air travel....
Just my opinion.
