Detroit Baseball questions

[Detroitdave]

Hello all ! two quick questions about the Detroit Tigers.
I'm not sure if anyone has ask this question before on this site , but I recently went to a Tigers game last week , with family and we noticed that I've never heard any Motown music being played at the games ? or any songs mentioning Detroit, besides, Journey's, don't stop believing .[[born and raised in south Detroit)
I know the players pick the songs they come onto the field too, and they use current songs also , but in a city RICH in music ,I rarely remember hearing Detroit artist ? .
Also watching the news today I saw that the tigers beat the Cubs in Chicago and when the tigers got a hit, and also when they won , half the stadium was standing and cheering for the Tigers ?
Is this because SO many Detroiters live in Chicago, are there really that many people from Detroit that we've lost to the windy city?
