All of Bryan Adam's music will always stay with me no matter how old I get. He was around before I was born, and I'll still listen to his music when I die.

As for the more recent, and since this is crunchyroll, I'll say BIGBANG's "Since 2007." I think I just keep going back to it because that group has changed sooooo much over five-ish years. I mean, doesn't the title speak for itself? It's cool to see BIGBANG then and now and it's surprising how I love "Since 2007" as much as I love "Tonight"
