While I'm on this guitar rock kick, here is the single I named the best of 1989..."Almost Hear You Sigh" by the Rolling Stones.
Although it only managed to peak at #50 on the U.S. singles chart, at the time of its release this was arguably the best Stones track since "Waiting On a Friend."
It's one of those "lost gems." Most people don't remember the song, but when they hear it they love it.
Enjoy.
