Stevie Nicks and her band Fleetwood Mac each had an impressive showing on the Billboard 200 album chart this week. Nicks' latest album, 'In Your Dreams,' debuts at No. 6, while Fleetwood Mac's classic 1977 album, 'Rumours,' somewhat surprisingly re-enters the chart at No. 11.

How does a 34-year-old disc land that high on the charts, you ask? Well, 'Rumours' benefited greatly from a May 3 'Glee' episode that devoted its entire hour to music from the landmark disc. That helped the album sell nearly 30,000 copies last week, and earn the highest re-entry on the chart since the Rolling Stones' 'Exile on Main Street' made a return appearance at No. 2 last year.

Meanwhile, according to Billboard, 'In Your Dreams' moved 52,000 units and became Nicks' fifth solo album to crack the Top 10. Her previous disc, 2001's 'Trouble in Shangri-La,' opened at No. 5. 'In Your Dreams' features the single 'Secret Love,' which was reviewed quite favorably on our site.

It's not all sunshine and flowers for Nicks, though. She was forced to postpone a few dates on her current tour because she came down with pneumonia and the flu. However, she has scheduled a special birthday performance for May 26 at the Wiltern Theatre in Los Angeles.
