I've updated the TWIS app's data to have the TWIS 2010 Science Music Compilation now that the album is available. Everything was going great, many of the contributing artists had iTunes pages and versions of the songs already in iTunes. Unfortunately when I went to test the app with the new data I discovered that the <store> tag in the TWISMusic.xml file was not being parsed at all so I can't link to the album link on twis.org so that app users can purchase the app. How embarrassing!
