Hey all. I thought it might be of interest to some folks here that the custom music/beat-mapping site for Syth Riders, known as SythRiderz.com ( https://web.archive.org/web/20241127043511/https://synthriderz.com/ )
An effort to archive the data, which includes over 3,800 custom songs + mappings, and is likely not going to be put back up can be found through here the discord link here: https://www.reddit.com/r/SynthRiders/comments/1it138p/synthriderz_down/
For anyone who needs it there are couple of magnets on Discord, which I won't provide (nor the discord invite) as they likely don't need additional outside exposure.
Probably a bit of a niche, but I'd hate to see it not get into the hands of those who need it.
Edit: Removed some inaccurate information.
