The Beastie Boys perform at Bonnaroo June 12 in Manchester, Tenn. Soon after, the hip-hop trio cancelled plans to tour and release a new album after Adam "MCA" Yauch was diagnosed with cancer.

After a slow week on the Billboard 200 albums chart where the top 10 didn't greet a single new entry, next week's tally should liven up a bit, thanks to bevy of new releases.

While Adele's "21" is on track to spend a seventh week at No. 1, the rest of the top five may be filled with debuts. The new "Now 38" compilation -- clearly released in time to profit from purchased made for Mother's Day this weekend -- could arrive in in the No. 2 slot. Industry sources suggest it may sell around 110,000 copies by week's end on Sunday, May 8.

Aiming for about the same sales launch is Beastie Boys' "Hot Sauce Committee Part 2," which will be fighting it out for the No. 2 slot.

Next in line could be Fleet Foxes' second full-length album "Helplessness Blues" (perhaps 80,000) and then Jennifer Lopez's "Love?" (60,000). Fleet Foxes' last album, its 2008 self-titled set, debuted at No. 83 -- though it eventually peaked at No. 36 the following year.

J.Lo's last English-language album, 2007's "Brave," bowed at No. 12 with 53,000 according to Nielsen SoundScan. Her new album is led by the single "On the Floor" (featuring Pitbull), which has so far peaked at No. 5 on the Billboard Hot 100 and shifted 1.6 million downloads.

Also aiming for likely top 10 entries are Stevie Nicks' "In Your Dreams" and Musiq Soulchild's "Musiqinthemagiq."

One notable re-entry next week might be Fleetwood Mac's "Rumours" album, which is profiting from the power of Fox's "Glee." The TV series dedicated its entire May 3 episode to the 1977 No. 1 album -- which spent 31 weeks atop the chart. Six of the set's 11 songs were performed by the cast, while another was heard in its original form as background music. Early sales projections from industry sources suggest it could move around 20,000, which could place it among the top 30 on the Billboard 200 next week.
