Which Glenn Frey song's lyrics say, "The sun goes down"?

The Glenn Frey song whose lyrics say “The sun goes down” is You Belong to the City. Frey co-wrote and recorded the song with Jack Tempchin during his solo career, and it became one of his best-known recordings outside the Eagles.

The song was written specifically for the television series Miami Vice and was featured in the 1985 episode “Prodigal Son.” Its atmospheric combination of synthesizers, saxophone, drum-machine textures, and urban imagery matched the show's stylish view of nighttime Miami and New York. Frey performed nearly all the instrumental parts himself, with saxophone supplied by studio musician Bill Bergman and drums by Michael Huey.

Released as a single in September 1985, the song reached No. 2 on the US Billboard Hot 100 and topped the Billboard Top Rock Tracks chart. It appeared alongside Jan Hammer's “Miami Vice Theme” on the Miami Vice soundtrack, which became a major chart success. Listeners sometimes confuse it with Frey's other Miami Vice hit, “Smuggler's Blues,” but the lyric about the setting sun belongs to “You Belong to the City.”
