Judging by the crowd jammed into the two soundstages at L.A.’s Mack Sennett Studios on Wednesday night, the organizers behind the Guild of Music Supervisors Awards are having a tough time keeping up with the increasing numbers of wannabe attendees. What started out as a brunch in its first couple of years has grown into a full-blown A-list event, with film and TV music pros of every stripe hobnobbing with the soundtrack curators who make their projects sing.

It was the third venue to host the ceremony in five years, and the second consecutive year for Mack Sennett, but demand is clearly exceeding the space, with the cocktail hour ultimately packed elbow-to-elbow.

There was the requisite lineup of celebrity presenters, including soundtrack legends Kenny Loggins (“Footloose”) and Ray Parker Jr. (“Ghostbusters”), but the real stars were the supervisors themselves, including Frankie Pine (who won for “Nashville”) and guild president John Houlihan — nominees who doubled as presenters. Thomas Golubić, the music supervisor behind “Breaking Bad” and its spinoff, “Better Call Saul,” held court like a rock star. Maureen Crowe, the guild’s first president and most ardent champion, darted about the room like a one-woman Greek chorus (she referred to PJ Bloom, who won for HBO’s “Normal Heart,” as “the Susan Lucci of music supervisors”).

All the while current Oscar-nominated songwriters Gregg Alexander (“Begin Again”) and Diane Warren (“Beyond the Lights”), as well as Oscar-winning composer Gustavo Santaolalla (“Babel,” “Brokeback Mountain”) worked the room; and bigwig composer/supervisor agent Richard Kraft looked like a kid in a candy store.

For all of the handlers, assorted musicians and studio, network and label execs trying to curry their favor, the supervisors themselves remain a rather self-effacing bunch. Winner Season Kent shook like a leaf upon receiving her award for “The Fault In Our Stars,” and JT Griffith, who won the brand laurel for Nike, joked about working on an ad “that ended up not running because the Oregon Ducks didn’t win the national championship.”

But to paraphrase Roy Scheider in “Jaws,” they’re going to need a bigger boat.
