Week of July 25

This week, with their ascension to No. 1, Barenaked Ladies have one of the 10 biggest "summer" songs in the roughly three-decade span of my charts. Here's how "Summertime" ranks as of this week, with "summer" songs defined as songs with the actual season in the title:

1. Endless Summer Nights – Richard Marx, 1988
2. Sausalito Summernight – Diesel, 1981
3. ’Til Summer Comes Around – Keith Urban, 2010
4. All Summer Long – Kid Rock, 2008
5. The Boys of Summer – Don Henley, 1985
6. Summertime – Barenaked Ladies, 2010
7. Hot Summer Nights – Night, 1979
8. Suddenly Last Summer – The Motels, 1983
9. Summer Son – Texas, 2000
10. Blame It on the Summer – Basia, 2009

Oddly enough, several of these songs (e.g., "The Boys of Summer," "Sausalito Summernight") were not hits in the actual summertime, but that didn't stop them from becoming successful. It looks like Sheryl Crow could join that club in the next few weeks as her "Summer Day" moves 27-21 this week.

Elsewhere, Pitbull enters the Top 40 for the second time in three weeks as a guest artist. While "I Like It," his collaboration with Enrique Iglesias, moves 31-28, his team-up with Usher leapfrogs his earlier hit by debuting at No. 27. "DJ Got Us Fallin' in Love" is Usher's third Top 40 hit in 2010, following "Papers" (No. 20 in January) and "Making Love (Into the Night)" (No. 23, last month).

Brandon Flowers debuts at No. 39 with "Crossfire." It's the first solo single for the lead singer of The Killers, who have hit the Top 40 four times, with their biggest single being "Read My Mind" (No. 2 in 2007).
