Wiz Khalifa's 'See You Again' Still the No. 1 Song of the Summer… So Far

At roughly the one-third mark through summer, the collab with Charlie Puth has led the Songs of the Summer chart in each of the list's first five weeks.

Just past July 4th barbecuing, the race for 2015's top song of the summer continues to smolder. Not that there's any dispute so far as to the leading candidate: Over the first five weeks of Billboard's Songs of the Summer chart, Wiz Khalifa's "See You Again," featuring Charlie Puth, has ranked at No. 1 in each frame.

So, roughly a third of the way through summer, the rap collab, which debuted on the Billboard Hot 100 back in March and reached No. 1 on the weekly chart dated April 25, continues to set the pace among summer's biggest hits so far. (The track has led the Hot 100 for 11 weeks running, leaving it a week away from tying the mark for the longest-reigning No. 1 by a rap hit all-time.)

The 20-position Songs of the Summer running tally (up from 10 in years past) tracks the most popular titles based on cumulative performance on the weekly Hot 100 chart from Memorial Day through Labor Day. At the end of the season, the top song of the summer will be crowned.

Below "Again" on Songs of the Summer, Taylor Swift's "Bad Blood," featuring Kendrick Lamar, ranks at No. 2 so far (and has held the runner-up spot behind "Again" each week). Fetty Wap's "Trap Queen" places at No. 3, followed by Walk the Moon's "Shut Up and Dance" (No. 4), with both hits also remaining where they were when Songs of the Summer launched four weeks ago.

Rounding out the Songs of the Summer chart's top five is a newer contender: OMI's "Cheerleader," which has vaulted from No. 16 on the season's first tally. (It ranks at No. 3 on the latest Hot 100, dated July 11.)

Can "Cheerleader" challenge "Again" before the end of summer? Or, does "Bad Blood" have enough momentum left to overtake the older "Again" on the Hot 100 and, eventually, Songs of the Summer? ("Blood" spent a week at No. 1 on the Hot 100 dated June 6, just before the Songs of the Summer started this year.) Even if either hopeful can, "Again" is likely to remain in the charts' upper reaches through summer, further solidifying its chances to take this year's title.

As the battle continues (along with, hopefully, more mouth-watering barbecuing; there's no rule that says that has to stop after the Fourth), keep checking out the Songs of the Summer chart, week-by-week, on Billboard.com.
