[I. Spaceman]

although it's good music, I just can't relate to it at all. 

I'll bet you're not a fan of Robert Johnson, then.

I think blues music is a little easier to relate to than songs about surfing and old cars I know nothing about...

[Summertime Blooz]

I know it's hard to imagine the group without them, but from experience, it seems non-fans of The Beach Boys are put off by the band's very early surf & car-oriented work. Although it's not all terrible, I can't say I blame them,

I'd say that's the understatement of the year.

To answer the original poster's question though, just hand them a copy of Pet Sounds. If that doesn't work then they simply can't be helped.
