Is that Chicago or REM? I can never tell which band (LOL)

Corey and I share an inside joke about REM and Chicago sounding alike.  In reality the two groups have different styles and sound nothing alike.  Their music sound is almost as similar as their group names. But there is a charming story behind our method of madness. 

One day Corey and our cousin, Earl, were listening to the radio.  One of REM’s songs came on and Corey asked Earl if he knew the name of the group that was performing.  Earl said that it was Chicago.  Corey, perhaps not as familiar with pop music as we both believed that Earl was, was somewhat familiar with Chicago and just didn’t think that sounded like them.

So Corey asked Earl about another song that he had heard REM sing.  Earl was still positive about the group being Chicago.  Later on Corey asked me about it.  And so whenever we would hear a song preformed by either REM or Chicago we would just look at each other and ask:  Is this REM or Chicago?
