Katy Perry 'Roar' Debuts at No. 85 on Billboard Hot 100, Top 10 Remains Same as Robin Thicke 'Blurred Lines' Holds at No. 1 for Tenth Straight Week [VIDEOS]

Though chart points have shifted slightly in the last seven days, the top 10 spots of the Hot 100 remain the same for Aug. 15 as they were last week, according to Billboard. This means, of course, that Robin Thicke's "Blurred Lines" holds at No. 1 for the 10th week in a row, making it the absolute undisputed hit of the summer.

"Blurred Lines" rose to No. 1 back in mid-June, knocking Macklemore & Ryan Lewis' "Can't Hold Us" from the top spot. "Blurred Lines" has kept other massive summer hits, such as Daft Punk's "Get Lucky," Miley Cyrus' "We Can't Stop" and One Direction's "Best Song Ever" stuck at the Nos. 2 spot while it gained radio airplay, streaming and video views (and controversy).

Miley Cyrus' "We Can't Stop" is still stuck at No. 2 this week.

Actually, "Blurred Lines" is only the seventh No. 1 track of 2013. The year began with Bruno Mars' "Locked Out of Heaven" for two weeks, followed by Macklemore & Ryan Lewis' "Thrift Shop" (four weeks, then two weeks), Baauer's "Harlem Shake" (five weeks), Bruno Mars' "When I Was Your Man" (one week), Pink & Nate Reuss' "Just Give Me A Reason" (three weeks) and, finally, the aforementioned "Can't Hold Us" (five weeks).

Next week, there may or may not just be a new No. 1. Katy Perry's first "Prism" single "Roar" made its Hot 100 debut at No. 85 this week, with only a few days of sales, streams and radio play taken into account. According to Billboard, the song is likely to shoot into the Top 10 next week and may even take over the No. 1 spot from the previously unstoppable "Blurred Lines."

Of course, fans cannot discount the new Lady Gaga single "Applause" either. Though the song failed to make the Hot 100 with its rush debut earlier this week, it's sure to launch into the top 10 next week as well, at the very least, knocking another song out of the top of the chart.
