Unfortunately, the OEM tracks are ported from POD OEM to work with the newer versions of POD and probably the AI from existing equivalent tracks was used. i.e. on GallOEM you see Gallery AI, on CityOEM you see AI from City. And becuase the OEM tracks have slight differences compared to the tracks GOG POD has, AI-s tend to bump into walls and get stuck more often and making the races dull.

I'm a bit rusty, but I think Escape was a community made track, and because the community doesn't have a tool to create new AI, specifically for Escape, they used an existing AI - I think it was the Pompeii one. So you end up having glitched AI, which is actually following the right Pompeii path... on a track that isn't Pompeii.

Everest, Forgetit, Newsanse, Eiscave, Bender and Antipod all suffer from the same problem. They are good tracks for online racing, ghosts and setting records.

Beach... hmm... it worked okay last time I played it. I'll have to test it.

About the songs.. I don't think there is a way of playing one song for one track and then another song for another track during a championship (e.g. play one song on Beltane and then another on Roc).

If you're in single race mode, the only way I know of is if you exit the game, change the race music .mp3 file with another .mp3 file, and then start the game again. Which is tedious :D.

POD loads all its sound files before the game starts and can't really be changed without restarting the game. At least not that I know of. :D

Thank you Darkriot, there's really no way. I moved in the settings to change the artificial intelligences and the songs but without success. The music works well when assigned to the podhacks, but without it, in championship mode tracks like road70 or factory do not play music or when it plays is already the end of the last lane (I do not know if it gave to understand well because of my little knowledge about English, and the translator does not help most of the time) all the artificial intelligences in the difficult way are persistent, less jos and slider that leave to desire.I already put good cars for them like arakn or lorismas does not solve.A beach track the cars stand Trapped in the "water" and toshio goes in the opposite direction. The only ones to complete beach are rage, nitro, slider, and antonio.
What I find strange is that forgetit is remade of tracks with support for artificial intelligence (Skyrace, magnetic, mine ...) But even then there is no way.

Sorry for the English bad, I'm trying to improve.
