There seems to be an issue with Firefox 126.96.36.199 and iTunes 7.6 on OS X with regards to M3U files. I've noticed this issue with eMusic as well. To solve this, I've included the URL of the actual streams, and if you enter that URL in Advanced --> Open Stream, that should work. There's also this script, but I haven't had a chance to try it yet.
Coil founder John Balance (a.k.a. Jhonn Balance) was killed on Saturday in an accident at his home. He was 42. Balance founded Coil in 1983 as a solo Psychic TV side project; Peter Christopherson joined in 1984.
