Decca Broadway's Wicked continues to remain atop the chart, a position it has held since the chart's debut in January 2006. Rhino's Jersey Boys and Mamma Mia! (also on Decca) are right behind.

Walt Disney's The Lion King — which jumps three spots from last week — and Decca Broadway's Spring Awakening round out the top five.

Ghostlight Records' The Drowsy Chaperone re-enters the chart at No. 14. Entries from last season — Legally Blonde (Ghostlight Records), Mary Poppins (London cast on Walt Disney) and Curtains ( Broadway Angel/Manhattan) — also appear on the chart.

Along with Wicked, the cast recordings of Mamma Mia!, Monty Python's Spamalot and Avenue Q have remained on Billboard's Top Cast Album Chart for the full 90 weeks since the chart's inception.

* Legally Blonde recently joined the company of those that have unseated the release of Stephen Schwartz's Wicked — which has topped the chart for 81 of the 90 weeks the chart has been published. The only other recordings to topple the stronghold are Spring Awakening, the Columbia Records two-disc "Harry On Broadway" release (with Broadway's The Pajama Game revival and selections of Connick, Jr.'s Thou Shalt Not) and The Color Purple for one week each. Jersey Boys enjoyed a four-week run at No. 1 following its Tony win and also reclaimed the top spot the week of Feb. 8.

Billboard added the Top Cast Albums chart to its listings Jan. 12, 2006. The chart measures sales of albums from stage musicals. Broadway recordings mostly fill the 15-slot table, but cast albums from other locales are also eligible. The addition of the chart to Billboard's 112 charts generates exposure for the genre which does not often chart on the Billboard 200. The Schwartz musical — which opened on Broadway in October 2003 (album released Dec. 16, 2003) — appeared at the top of the first chart.
