It isn't a classic sign of depression. Maybe you are just feeling at a low time in your life right now, and reflecting on your life to help put things into perspective. To be honest , it can be a release listening to songs you can relate to, as we all need space on our own to think about our past. It can be likened to a sort of therapy. I do this whenever i feel down, it helps me to release tention.
As long as it doesn't put you in a constant depressive mood or causes you to dwell on things for weeks , then i'd say it is okay to do.0
