I just want to point out however old you think you are, add five years to that and thats where we all are right now.

Thats Rob Thomas reflecting on the 20th anniversary of Smooth. Its hard to believe, but the hit Santana song that Thomas co-wrote with Itaal Shur, which swooped up three Grammy Awards and spent 12 consecutive weeks at No. 1, is turning 20 this year.

Even Thomas feels old thinking about it.

Literally four nights ago, I was talking to Carlos [Santana] about it, like this crazy thing, Thomas told HuffPost in a Build Series interview. Oh yeah, that happened a lot longer ago than we remember it. It feels like we were just out a couple of summers ago premiering it for people on the road.
