The longest streak of songs with years as the titles we can get

Chaos A.D. - Sepultura

Just need to figure out what year “Chaos” represents.

We’ve already covered the year, but:

1984 - Van Halen. It’s not just the title of the album, but also the title of the first track. Is that a twofer? Shoot, it was also released in 1984.

1984 seems to have been a popular year.

I remember the actual Summer of '69. And it wasn’t about the year for anyone.

Yeasayer: 2080

I think you’re reading a lot more into the song than is meant to be there. It’s not a biography. “Summer of '69” just sounds better than “Summer of '77.”
