The last time I checked most of the tracks seemed to be in-file names, so thanks to the person who fixed it! It was kinda confusing to find the track I wanted...

On this site, almost all music tracks that loop do not do so properly at all according to how they loop in-game. They play once and then fade out right where the looping point would start. It applies to every music track here, but on YouTube the issue is drastic in regards to Apple Scramble 2, Coin Clash 2, Attack Riders 1 & 2, basically all of Crazy Theatre, Rocket Rumble and Slam Hockey 1 & 2, as they do not loop properly at all, cutting off right where the music would start looping. More info at the bottom of this post.

Lastly, all of the names on the site currently are incorrect. This is how they're referred to either in this game's Sound Test or elsewhere, where applicable:
• Left = fan name
• Right = official name [N/A means not officially named in English at the time of post]
• * = worst offenders of music not looping properly

If anyone's skeptical, I'll eventually link to a video showing almost all of the music tracks and how they SHOULD loop. Once done, one of two things should ideally happen:
1) Someone with fancy audio-editing equipment can view the video, rip the audio from the game, make the needed changes according to the video and then upload the new audio to the site at 44.1 or 48 kHZ.
2) Someone with a 3DS capture card can record all of the music straight from the Sound Test, as that's exactly how the music should sound in-game. After recording, they would save each music track separately in an MP3 or WAV file or whatever at 44.1 or 48 kHZ and then upload it to the site.

WARNING: Don't upload the audio at 32 kHZ only -- it causes problems on Macintosh computers.
