I think richie345 is pretty close to getting it right. Nice job! But I'd like to add that there's a great double bind in the first line:
On the one hand, when you get older you start to feel like your teenage years were the time when you were happy. In a long relationship that's going down the tubes, you start to feel like the early days were when you were happy. When you were younger, you listened to sad music because you weren't actually sad. You paid money for the thrill of pretending to be sad. As a grownup, you know about real sadness. Being a grownup sucks.
But on the other hand, when you were younger you actually did feel sadness more intensely. Music really mattered. When your long relationship started, you felt those emotions really intensely, and music was crucial to you. But then you get older and nothing seems to matter as much. Your relationship gets boring. Everything gets dull, and you wish for some real sadness. You don't bother to keep up with new music anymore. Being a grownup sucks.

Both meanings operate at the same time.
