Not “songs with a city name in the title”! The title must be nothing but the name of a city. I will also allow city + state or city + country. So “I Love L.A.” or “St. Louis Blues” does not count, but “New York New York” does.

And somewhat of a reach, the traditional song 'Botany Bay, which was what Sydney was known as before it was established as a distinct place [Sydney’s official name was then ‘New Albion’, which was never used].
Would the OP count “Istanbul (Not Constantinople)” 
According to Wikipedia, at least 8 different musicians have written songs titled “Chicago”.

“Panama” by Van Halen technically qualifies. (The name of the city is just “Panama,” not “Panama City,” the same as the country. Also, the song is actually about a car, but the OP didn’t say the song had to be about the city.)
There are at least two called ‘Reno’.
