The game's main theme, a snazzy remix of the title theme from the original Plants vs. Zombies.
Garden Warfare and its sequel use licensed songs to a great extent in trailers. One particularly awesome usage is the zombies interrupting Grieg's "Morning Mood" with Airbourne's "Firepower" during the first trailer introducing them as playable. The best part is when the lyrics briefly line up with what's happening onscreen; "I've got the ammo to go all night" is sung when All-Star is firing his Football Cannon, which has Bottomless Magazines.
Any of themanytracksthat play during the final stage of Gardens and Graveyards stages, setting you up for, depending on your side, a final push or a last stand.
The twosongs that play either during the escape phase of Garden Ops or when a team is ten away from 50 vanquishes in Team Vanquish. They're incredibly suspenseful and essentially tell you to buckle up, because these last few minutes are going to be painful ones.
This song that plays while near an uncontested garden in Gardens and Graveyards. It's hilariously out of place considering there will generally be rockets, sniper rounds, and airstrikes flying all over the place at that time.
PvZ March from Garden Ops gets a mention too. It's a great marching-band-esque style song that prepares you for the Special Waves and their Elite Mooks.
Pretty much every single Super Boss Wave theme from Garden Ops.
Disco Zombie gets Boogie Your Brains Right Over Here, a great song that takes everything great about 90's disco and turns it into a boss theme, which fits perfectly for the hilarious yet deadly boss that is the Disco Zombie.
IceIce Yeti, the Yeti's theme, a quiet but intense theme with various tribal-sounding percussion for when you're battling a small army of the game's resident Goddamned Boss.
The Gargantuar's theme, a terrifying, percussion-heavy song designed to strike fear into even the most seasoned of players. The Zombies ominously chanting in the background just scream "run or get annihilated".
This glorious remix of Edvard Grieg's "In the Hall of the Mountain King" plays while chasing down the elusive Treasure Yeti. It just screams "Get him and steal all his money before he gets away!" It was so damn good that it also plays in the final objective in Zomburbia Turf Takeover stages in the second game.
The theme of the Z7 Mech from Citron's campaign is a great song that screams "dangerous boss".
The theme of the Giga Torchwood and Big Stump, a tribal-style song that gives the feeling of being hunted down by the wooden menaces that the two bosses are.
Super Bean's theme, which is just like a superhero theme, but with darker elements...because this time, you're the one fighting the hero.
The theme of Captain Smasher at the end of the Plant Campaign. A menacing, more naval-sounding piece for the undead pirate juggernaut he is.
The song that plays during the battle against the Sunflower Queen and the Royal Hypno-Flower. It's a suspenseful and menacing piece that sends a message that these bosses are perfectly capable of beating you and will show you no mercy.
Allfourphasethemes of the Mega Zombot 6000 at the final stage of Zomboplis. All four are menacing and incredibly heart-pounding techno/percussion songs that show that the Zombies' new superweapon is not to be trifled with. The songs even gain intensity the more damaged the Mega Zombot is.
Allofthe the guitar-laden themes for Infinity Time. The themes when you fight the Gnome Kings areevenbetter.
The suspenseful song that plays during the Boss Hunt Missions. The theme for when the fight reaches a critical phase is even better.
