If Daft Punk's new hit "Get Lucky" really becomes the No. 1 song of the summer, Shazam fans can build an even stronger case that there's more to the music identification app's predictions than mere good fortune.

For the second straight summer, Shazam has released a top 10 list anticipating the summer's big hits.

More than 300 million people worldwide use Shazam to identify, or "tag," songs playing around them in bars, in stores and on the radio. The mobile app determines its top 10 based mainly on the number of tags the songs have tallied in recent months.

For example, "Get Lucky" has received 4 million tags and shot to No. 1 on Shazam charts in 91 countries.

Last year, Shazam correctly predicted Gotye's "Somebody I Used to Know" as the No. 1 song of the summer. It wasn't that big of a stretch — ­"Somebody" had already spent 19 weeks on the Billboard Hot 100 and five weeks at the No. 1 spot ­— but Shazam got serious props for it.

Will Shazam's predictions prove to be even more on the number this summer? It has tallied more than a billion tags since the beginning of the year, an increase of more than 80 percent compared with this time a year ago. Since last year's list was released, three out of every four top songs in the Shazam U.S. New Release Charts have gone on to reach Billboard's top 10.

KDWB DJ Lucas Phelan thinks Shazam's picks reflect overall sales, but he's not so sure about its ability to forecast hits, particularly regionally.

"I think Shazam is more for music heads, for people seeking out that tip-of-the-sword situation for the newest, coolest thing," he said.

According to Shazam, this summer's "Somebody" is supposed to be Passenger's "Let Her Go." Like the Gotye hit, "Let Her Go" has blown up in Australia and picked up 3.8 million tags globally. Shazam has it ranked No 2.

Other songs on this summer's list include Icona Pop's "I Love It" (No. 3), which became popular after playing on the HBO show "Girls," and Robin Thicke's "Blurred Lines" (No. 4), which Phelan thinks will be a KDWB mainstay and which he called his current favorite song.

Here are the top 10:

1. "Get Lucky," Daft Punk

2. "Let Her Go," Passenger

3. "I Love It," Icona Pop

4. "Blurred Lines," Robin Thicke

5. "Fall Down," will.i.am with Miley Cyrus

6. "Alive," Krewella

7. "Young and Beautiful," Lana Del Ray
