Well. The context is that those two songs exemplify the qualities that the bands fans admire in them. Def Leppard something to make the day pass by a little more smoothly, without having to think too much about anything. Cheap Trick showing you something new, challenging you and offering excitement. I could give you chapter and verse on songs and context for both bands, but it would bore.

There's a place for Def Leppard - i don't regret the money I've paid to see them, but I'm not going to get anything new from a third show I didn't get from the second.
