That looks good until you see that it needs fmod, which is non-free. Shame, otherwise I would have installed this
wxMusik and fmod are available in AUR
you can also try:
- madman, available in AUR [unsupported]
- rhythmbox, available in [extras]
- quodlibet, available in [community] (easyier to install)
EDIT: just search iTunes in the official and AUR packages!
All your base are belong to us
