Hi, during development of a OC ReMix download script (https://ramis84.github.io/OCReMixDownloader/), i noticed that a lot of downloads did not match the MD5 hash on the site. Below are the statistics for the last 100 OC ReMixes I ran through for all available mirrors on the site. ocr.blueblue.fr seems to be always matching, but there are a couple of hashes failing on iterations.org, and most of the downloads from ocrmirror.org did not match. Statistics OCR04198-OCR04297: ocrmirror.org. Successes: 31, FailedHash: 69 iterations.org. Successes: 98, FailedHash: 2 ocr.blueblue.fr.

Thanks a lot @Ramaniscence, I was not aware of the correct verbiage, and have corrected all references in the project (hopefully it is correct, please correct me if it is still wrong). MD5 checksum verification should not be too difficult to implement, so I will look into that. Using the alternative mirrors in a random order is also a reasonable idea, currently it only uses the mirrors if the first one fails. Regarding the RSS Feed. I only use it for fetching the latest song number, then the script fetches each song page separately, since the URL format is fixed. UPDATE: I have now implemented MD5 checksum verification, and shuffled the order of used alternative mirrors to distribute load on servers. The new version is available on the site.

Hi guys, I have made a cross-platform (Windows, Linux, macOS) command line tool/downloader for automatically downloading songs from OCRemix, which can be run once, or on a schedule to always be in sync with the latest remixes. The application & source code are on GitHub, and I would love to have your feedback if you have any suggestions for improvements: Homepage: https://ramis84.github.io/OCReMixDownloader/ GitHub: https://github.com/Ramis84/OCReMixDownloader/
