I try install CLAM Annotator application, but it has libqt4-opengl problem (and others). On Mint distribution everything work OK. This application is beautiful. How it work: I open "chords.pro" (one of its project example) and add some music file (mp3...) on "Song Descriptor" tab. Next step is "Compute Descriptors". End of file will make error (program is on 0.4 version and has bugs...). Ignore it. On "Intrasong Descriptor" can start song. It will play with graphical chords viewing. Great tools for analise chords from some song. I would like to have it on 64Studio.
