Pink Floyd lryics are definitely depressing. When you first hear them, you overlook this because you are awestruck by their relevance, F__ing brilliant interactions with common, everyday sounds and how this combination creates deep philosophical meaning (aka smoking a joint.)
Eventually, you get a bit older and and you experiment in some other musical genre that has less to do with musicality but all the ladies are listening to it and think it's cool to dance to (aka you are scarfing down beer and shooters at the bars like crazy in between dancing like a rooster on crack in hopes of getting laid.)
Then as you grow older yet again, the lyrics begin to relate to events in your life and you find them very sad but in an oddly comforting way (aka you drank too much beer while avoiding your family by pretending to work on your mid-life crisis car in the garage.)
Finally, the lyrics hit home and you can no longer bear to listen to them, even though you now truly appreciate the musicality and artistry (aka Now the kids are gone but you fall asleep after three scotch after dinner and don't know anyone who sells weed anymore.)
With great power comes Awesome irresponsibility.
