This answer was in the first link thread. Apparently, Myspace does not like programs which do not have a flash file in the program, somewhere. Firefox and Seamonkey go outside, and use Flash directly. That's not the case with Chrome and IE. Myspace urged me to login, or go through Facebook, but I have not bothered doing that. One does not have to login Myspace to play music, using Chrome, and, probably IE.
Since, I do not even know if it would work, I am not pursuing the matter any further.
To me, it seems to be a combination of issues, and Myspace seems to be the worst culprit.
I got it! I signed up to Myspace, and I am listening to music, now, using FF11. It will not work, unless I login!
