What is the name of the word for discovering a great song that came out 17 years ago for the first time.

In the fall of 2011, FX in their previews for Rescue Me season premiere  began playing a song that I never heard of before, I went on you tube and found it - it was Pearl Jam's Elderly woman at the counter. I believe this song came out in the 1990s. Then for previews for the premiere of Anarchy on  FX they began playing a Red Hot Chili Peppers song I never heard of called Doni California (I think). Both of these are great songs. It is just hard to believe that they came out years ago. I never heard of them before.

In the last couple of weeks I found 2 other songs on you tube that I don't believe that I ever heard but they are just awesome. (the songs are even better when you can read the lyrics.)

They are is "found out about you " by the Gin Blossoms and "Desperately Wanting" by Better than Ezra. But what really shocks me is that these songs came out in the mid 1990s. I am in shock, how did I miss them, what was I doing. In fact, I am a little sad because I sort of missed their heyday (by an awful long time). In particular,  The Gin Blossoms seemed to have a bunch of great songs that I just missed.

There are a lot of performances on Leno and Letterman and the Hard Rock Cafe (VH 1?) on you tube of these type of songs that make me feel nostalgic for a time that I lived in but completely missed.
