by Tiana Feng As a music blogger I’m always looking to expand my library. Tune Glue is a web based application that is a music map that helps you discover new and similar artists. How it works is that you type in an artist in the search bar, expand it and you start with 6 artists that are similar to that artist. You can then expand each of those six artists and get more results and so on. Some of them have links to pages and songs where you can learn more. It’s a pretty interesting and nifty little thing. For some reason I also find it amusing to drag things around.
