AllMusic offers various feeds to help you keep up to date with new releases, articles, and staff picks in the reader of your choice.
RSS stands for Really Simple Syndication, which is standardized content distribution method that can help you stay up-to-date with your favorite content online. Once you follow a feed, instead of having to visit a site daily and see if there are new posts, an RSS reader will notify you when new content has been published.
An RSS reader will notify you if new content is available on the feeds you follow. From here you can use your RSS reader to view the content provided, or to go to the website to find out more. As you read each piece of new content the RSS reader marks that content as read.
There are many RSS readers available, but some of the more popular ones include Feedly, Inoreader, and Newsblur. For more info on these readers, you can find more details in this Wired article. Happy reading!
