Lionel Richie performs at the SXSW Billboard 2012 Showcase at ACL Live in Austin, Texas on March 14th.

Lionel Richie's "Tuskegee" album holds at No. 1 for a second week on the Billboard 200 chart, shifting 114,000 copies according to Nielsen SoundScan (down 11%). The pop veteran blocks Jason Mraz from earning his first chart-topping, as "Love Is a Four Letter Word" starts in the No. 2 slot with 102,000.

Still, congratulations are in order for Mraz, as "Love" notches both his highest chart rank and his best sales week yet. His previous high came with 2008's "We Sing. We Dance. We Steal Things.," which debuted and peaked at No. 3 with 73,000 in its first week.

Adele's "21" falls 2-3 with 90,000 (down 2%) while Train's "California 37" rolls in at a career-high No. 4 with a 76,000 opener. The band has claimed three previous top 10s, but this is the group's best showing yet on the tally. The album follows its last studio album, 2009's "Save Me, San Francisco," which debuted and peaked at No. 17 with a 27,000. That set spawned Train's biggest Billboard Hot 100 single, the No. 3 hit "Hey, Soul Sister."

One Direction's "Up All Night" holds at No. 5 (55,000; down 18%), Nicki Minaj's "Pink Friday: Roman Reloaded" falls 3-6 (48,000; down 40%) and Gotye's "Making Mirrors" is steady at No. 7 (44,000; down 18%).

Rapper Future debuts at No. 8 with his first studio set, "Pluto," selling 41,000 in its first week. He's released numerous mixtapes since 2010 and has notched eight hit singles on the Hot R&B/Hip-Hop Songs chart. Two of those climbed all the way into the top 10: "Racks" (YC featuring Future, No. 6) and "Magic" (No. 10).

Bonnie Raitt's "Slipstream" slips 6-9 in its second week (35,000; down 45%) while Luke Bryan's "Tailgates & Tanlines" returns to the top 10 for the first time since September, rising 13-10 (28,000; up 11%).

Over on the Digital Songs chart, Maroon 5's "Payphone" rings at No. 1, debuting with a whopping 493,000 downloads in its first week. The track, featuring Wiz Khalifa, notches the best-ever sales week for a digital song by a group, surpassing the 464,000 rung up by the Black Eyed Peas' "Boom Boom Pow" when it debuted at No. 1 on April 18, 2009.

Last week's No. 1, Gotye's "Somebody That I Used to Know" (featuring Kimbra), falls to No. 2 with 463,000 (down 15%) while Fun.'s "We Are Young" (featuring Janelle Monae) drops a rung to No. 3 with 251,000 (down 25%).

Justin Bieber's "Boyfriend" holds at No. 4 (235,000; down 8%), Carly Rae Jepsen's "Call Me Maybe" is steady at No. 5 (221,000; down 3%) and One Direction's "What Makes You Beautiful" slips 3-6 (196,000; down 27%).

Flo Rida's "Wild Ones" (featuring Sia) is a non-mover at No. 7 (170,000; down 9%), Nicki Minaj's "Starships" falls 6-8 (152,000; down 25%), the Wanted's "Glad You Came" is down one to No. 9 (148,000; down 18%) and Train's "Drive By" rises 12-10 (146,000; up 23%).

The chart's second-highest debut arrives at No. 11, where Linkin Park's "Burn It Down" debuts with 115,000. It's the first single from the band's forthcoming album "Living Things," due out June 26.

Data regarding overall market volume is delayed at the present and will be added to this story at the earliest possible time.

Next week's Billboard 200 competes with the same week in 2011 when: Adele's "21" held at No. 1 with 124,000 (down 19%) while the chart's highest debut was way down at No. 16. That was where Explosions in the Sky's "Take Care, Take Care, Take Care" bowed with 19,000.
