I’ve taken the “plunge” and joined emusic.com for three months. If you’re into mainstream, stay away… if you’re into somewhat more interesting music (Funker Vogt, Covenant, Front Line Assembly, Napalm Death, some more relaxed stuff I don’t know) this is definitely worth it.
Otherwise, I’m trying to finish an article for the SPIE before I can get back to yummy volume visualisation and musculo-skeletal modeling.
