Updated the Scritch player previews

Hey all! I updated the Scritch player preview folder to only include SOME of the old songs instead of all of them. I discovered that Scritch was downloading over 250mb to preview songs and... well, that kinda sucked 😅 Right now it's still a beefy 80mb, but should be a bit easier on less powerful computers.

As always, thanks for your positive feedback on this project! I'll continue to streamline the process and make it easier for everyone. All the best!
