A cool thing in Forza Horizon 4 was that you could make your car horn play snippets from Halo, Killer Instinct and Sea of Thieves. Clearly, this was a beloved feature as all those car horn themes are back in Forza Horizon 5, but have got company from more classic Xbox Game Studios franchises.
This was noted by VCG, that has listed all your options, which now includes favourites like Banjo-Kazooie, Doom (which sound incredibly cool!) and Ori and the Blind Forest:
Halo
Sea of Thieves
Killer Instinct
Ori and the Blind Forest
Banjo-Kazooie - Spiral Mountain (part 1)
Banjo-Kazooie - Spiral Mountain (part 2)
Battletoads
The Outer Worlds
Doom - E1M1 (high part)
Doom - E1M1 (low part)
