To complement my previous post, I've also finished putting together a complete & lossless set for Lego Racers, based on the audio files from the N64 & PS1. When there was a discernible difference between the two, I included both versions, for posterity. The N64 has superior audio at 44.1kHz over the PS1's 37.8kHz (I converted these to 44.1kHz with SOX), and the PC's 22.05kHz, which I used none of, but lacks the "punch" from the PS1 & PC versions. I ordered the tracks based on how the gameplay flows, so you can listen to it from start to finish and feel like you're actually playing the game. I added the win jingles at the very end because they don't really fit anywhere. The N64 tracks loop for 3 minutes then fade out, everything else loops once and has a clean ending.
73 tracks total with custom album art. Tracklist in the spoiler tag.
