What does "alley" mean? What kind of places can be called as "alley"?
In this context, "alleys" refers to the narrow passage or lane between or behind buildings. They are usually quiet, dark, and narrow, so they are often associated with being scary or dangerous. For example, robberies and crimes might take place in these areas, as there generally isn't a lot of foot traffic or surveillance. When Selena Gomez says that she's been "down the darkest alley," she means in a metaphorical way that she's been through scary and dark situations in order to reach her lover. Ex: I got robbed in the alley behind school. Ex: The alley was dark and a little scary. People usually avoided it unless they wanted to take a shortcut.
