I knew I recognized that song!

I noticed that too. We are the oldies my friends. Old gamers with a passion. I think its from the race with cletus in the first bart section of the game.

I waslistening to the engi play the music and the actual song playing in the backround =)

Well, in the event this taunt becomes official, here's The Simpsons: Hit & Run's entire audio library to get your hands on the music as demonstrated: https://psteamcommunity.yuanyoumao.com/groups/bizarchivistsoundproject/discussions/2/152391995421805610/

The one you'd be looking for is "banjo_main.rsd". It also has three "banjo_end" versions for even more delightful results. These RSD files can be opened & played with VLC Media Player or Audacity, the latter can convert them straight to WAV (Make sure it's in 16bit and 44100hz/44.1khz), ready to be renamed & slapped into a VPK for your enjoyment.

It is also in level 4 i think

I fear that due to this, Valve might change the song to something else when this gets accepted in game to avoid copyright issues just like they did with the Bag Pipes even though that has no reason to have it's music changed for the ingame version.

EAT PICKUP CITY FOLKS. And what do you know, i was just listening to the whole Simpsons Hit n Run soundtrack earlier today

Xd. Its a good game no matter what anyone says! Such a classic :p
