Jason Mraz's new album "Love is a Four Letter Word" is in the running to become the singer/songwriter's first No. 1 next week on the Billboard 200 chart. That is, if Lionel Richie's "Tuskegee" steps aside.

Both albums are on track to sell around 100,000 copies by the end of the tracking week on Sunday, April 22 -- so say industry sources. Richie's "Tuskegee" album topped the Billboard 200 for the first time this past week, selling 129,000 copies according to Nielsen SoundScan.

The new Billboard 200 chart's top 10 will be revealed on the morning of Wednesday, April 25.

Mraz has so far peaked at No. 3 on the Billboard 200 with 2008's "We Sing. We Dance. We Steal Things.," which started with 73,000 in its first week. If Mraz's new set moves 100,000, it will mark his best sales frame yet, surpassing the bow of 2005's "Mr. A-Z," which launched at NO. 5 with 81,000.

Also headed for a top five bow next week is Train's "California 37," which could start around Nos. 4 or 5 with perhaps 70,000 sold. It could result in the band's highest-charting album yet. They've gone as high as No. 6 -- twice -- with "Drops of Jupiter" in 2001 and "My Private Nation" in 2003. The act's last studio album, 2009's "Save Me, San Francisco," debuted and peaked at No. 17 with a 27,000 first week according to SoundScan.
