Aaron Boodman has posted a screenshot of Muse.net (coming Monday apparently). This is a web based mp3 organizind application which is SOAP based and w/ an open API that looks like it does some very cool stuff (very similar to the stuff I’d started working on, but much farther along). The great thing is the open API however. Once of the developers is Ian Rogers, who used to work at Nullsoft.
Here’s Ian’s Music Collection and a link to the Muse.Net PHP SDK. I’m really interested in the project, and would be interested to know if they plan on having different pricing schemes for where your tracks are being stored / streamed from and if you just want to do digs with their API’s?
