Each Friday, Billboard presents Tomorrow's Hits, a weekly look at new and noteworthy acts making their way toward Billboard chart success.

Ryn Weaver
When pop singer/songwriter Ryn Weaver appeared in June 2014 with her single "OctaHate," she quickly hit No. 1 on the Billboard + Twitter Emerging Artists chart. Now, the 22-year-old is translating that social success into budding airplay at pop 40 radio. Weaver's debut full-length album The Fool is due June 16 through Benny Blanco's Mad Love label, through Interscope. –Keith Caulfield (@keith_caulfield)

After scaling Billboard's dance/electronic charts, Swedish duo Galantis is crossing to pop radio with "Runaway (U& I)" (Big Beat/RRP). The frenetic track reached No. 8 on Dance/Mix Show Airplay and No. 15 on Hot Dance/Electronic Songs earlier this year. You've known the pair's talents for a lot longer, though: Christian "Bloodshy" Karlsson co-wrote Britney Spears' "Toxic" and Linus Eklow co-penned Icona Pop's "I Love It." –Gary Trust (@gthot20)

Greg Holden
Singer/songwriter Greg Holden makes his Adult Alternative Songs chart debut as "Hold On Tight" (Warner Bros.) starts at No. 30. The folk-pop tune features a heartwarming video that depicts a series of strangers paying it forward. The Brooklyn-based Brit is perhaps best known for co-writing 2012 American Idol winner Phillip Phillips' smash "Home." Holden's major-label debut album Chase the Sun arrives Tuesday. –Emily White (@emwhitenoise)
