Query: They were once a great band

As the title of my review says, Styx was once a great band. And this greatest hits CD proves that notion. Great songs like Grand Illusion, Come Sail Away, Too Much Time On My Hands, etc. Styx had three great lead singers in Dennis, Tommy, and JY. And they had class. These guys really need to hang it up, though. Ever since they became a Van Halen-wannabe band, (re: when they kicked Dennis out.) I have lost all respect for them.
