Ready to begin her last leg of touring in support of the 2003 Arista album "Afterglow," Sarah McLachlan says she is planning to rework aspects of the set list. The outing begins April 12 in Victoria, B.C., and will run through June.

"I only have so much to choose from," the artist tells Billboard.com. "I have the songs that I love to play and I have the songs I would be happy to never do again. I have to be honest to myself but also take into consideration what the fans are going to want to hear. And I'm very conscious of the fact that even though these are secondary markets, we are doing New York again, we are doing Los Angeles again and I don't want to put on the same show, so we've reworked some of the songs."

McLachlan says she is considering three possible additions to her "broken-down part of the show": new album track "Time" and catalog gems "Good Enough" and "The Path of Thorns," which will be reworked into "a very sort of folky, natural state."

By the time the tour closes, McLachlan will have been on the road for 20 months. Having entered motherhood in 2002, it appears her next project is baby No. 2.

"Most definitely, but that doesn't mean I'm not writing songs," McLachlan says. "My goal this summer is to not make any plans and it's a luxurious position to be in to say that I can take a couple of months off and I just want to... float. If I want to write then I'm going to write. If not, then I'm not going to put any pressure on myself to do so."

She adds, "I think everybody has gotten pretty used to the idea that it's going to take me five years between records. I'm not really interested in pounding the mud every year and a half."

Having already released the concert DVD/CD set "Afterglow Live" from her 2004 tour, McLachlan hints fans could see a best-of set before another studio album hits the streets.

"My manager and I have talked about that as a way to bridge the gap between the next album, which is going to be a few years away," McLachlan says. "I don't know; that kind of scares me. Isn't that the end of your career to do a greatest hits? I don't know. Do I have enough hits to be a greatest hits record?"
