Note: Track positions 26 and 32 are featured as special extended/rare edits in the compilation’s expanded edition, with Track 26 as a remastered radio edit and Track 32 as a collector’s extended club mix.

While the music is from the 1980s, the 2021 release date is significant for audio quality. By 2021, remastering technology for 80s analog recordings had peaked. This collection benefits from modern "loudness" standards while retaining the distinct analog warmth of 80s production.

Since no official tracklist exists publicly under that exact name, we can reconstruct what a credible “Giga Hits” should include based on 80s chart dominance, licensing feasibility, and digital compilation trends. A typical volume would feature a mix of synth-pop, rock, new wave, and one or two power ballads.

Here’s a plausible 32-track lineup that would justify the “Giga” label:

Side A: The Synth & New Wave Giants

Side B: Arena Rock & Pop-Rock 9. Bon Jovi – Livin’ on a Prayer (1986) 10. Journey – Don’t Stop Believin’ (1981) 11. Survivor – Eye of the Tiger (1982) 12. Europe – The Final Countdown (1986) 13. John Parr – St. Elmo’s Fire (Man in Motion) (1985) 14. Kenny Loggins – Footloose (1984) 15. Billy Idol – Rebel Yell (1983) 16. Rick Springfield – Jessie’s Girl (1981)

Side C: Dance, Funk & Pop Icons 17. Michael Jackson – Billie Jean (1983) 18. Madonna – Like a Virgin (1984) 19. Whitney Houston – How Will I Know (1985) 20. Prince – 1999 (1982) 21. Cyndi Lauper – Girls Just Want to Have Fun (1983) 22. Irene Cara – Flashdance… What a Feeling (1983) 23. The Weather Girls – It’s Raining Men (1982) 24. Lionel Richie – All Night Long (1983)

Side D: Power Ballads & Slow Burners 25. Foreigner – I Want to Know What Love Is (1984) 26. REO Speedwagon – Can’t Fight This Feeling (1984) 27. Berlin – Take My Breath Away (1986) 28. Starship – Nothing’s Gonna Stop Us Now (1987) 29. Chicago – You’re the Inspiration (1984) 30. Heart – Alone (1987) 31. George Michael – Careless Whisper (1984) 32. Phil Collins – Against All Odds (Take a Look at Me Now) (1984)

That’s a giga list. Notice the clustering around 1983–1986 — the commercial peak of MTV and CD adoption.
