muspy is a website that notifies you when your favourite artists release new albums. muspy is free software released under GNU AGPL.

Today I'm happy to announce the availability of the muspy API. The API allows you to create and modify user accounts, to manage the list of artists you want to follow and to receive their releases.

Someone is already working on an iPhone app that will use the API, expect more news on this front soon!

muspy is a free / open-source album release notification service.

To make it easier to populate the list of artists you want to follow, muspy allows to import top artists from your Last.fm account. Today this function became more flexible: in addition to getting overall top artists, it can now import most frequently listened artists in the last 12, 6 and 3 months and 1 week.

I also lifted the limit on the number of artists that can be imported from 200 to 500, and increased the number selected by default from 50 to 100.

Do you have a feature that you want to see in muspy? Let me know! Alternatively, feel free to fork muspy on GitHub and to send your pull requests.

If you are a music lover and never tried muspy before, give it a go! With muspy you will not miss an album release ever again.

muspy is an album release notification service, you give it a list of your favourite artists and it sends you a notice (by email or RSS) as soon as they have new releases.

I wrote muspy 3 years ago to scratch a personal itch -- I was spending too much time online checking if bands I'm into have something new; but was still missing many releases.

muspy was initially developed for Google App Engine, which was the hot new thing back then. In retrospect, while working with App Engine was extremely educational and a lot of fun, it wasn't a very good fit. The recent announcement on the price increase was the last straw -- I decided to re-write it in vanilla Django and to host it myself.

I'm also releasing the source code under GNU AGPL in the hope that it will be beneficial for the service and for its users.

Major changes since the previous version:

• Track release groups instead of releases

  This was the most frequently requested feature, there were too many duplicate releases for some artists, release groups make everything much cleaner. This change was also the reason why the new version is almost a complete rewrite.

• Stars are off by default for new releases

  muspy allows to star individual releases, starred releases show up on top of the sorted list of releases. This feature wasn't used by many which resulted in all releases being starred for most users. Now stars are off for new releases, if you want to star, you have to do it manually on the website. I migrated stars only for users with S \< min(R, 40) / 2, where S is the number of starred releases and R is the total number of releases for all artists you follow.

• Speed

  It used to take more than a week to check all artists for new releases, now the checking cycle is much shorter. Things like importing from Last.fm or adding a comma-separated list of artists should also be significantly faster.

• Blog

  I will be blogging about muspy blog instead of on the website itself. Feel free to subscribe to the full feed or just to the muspy category.

Other than that, muspy remains pretty much the same. I migrated all the data but I encourage you to go the old site at muspy.appspot.com and to check if everything was migrated correctly. Please note that the old site's background processes are not running and it will be taken down in a month or two.

Now that muspy is free and open-source, don't hesitate to look at the code, tweak it and suggest improvements. Git and GitHub make it too damn easy!

And if you never used muspy before, give it a try!
