PS: When you start a topic, you do not have to make a new
one just to add to the discussion; thought I'd add that little
bit of information, so as to point out your primary posting
here has been +one post spread over four+ for the most part...
...and if you spell out what it is you are doing, the hardware
and software you are trying to do (whatever) it is, with, the
general answer would be more forthcoming.
Had you stated you were trying to open an .exe music file
from some free(?) music downloads site and the Safari
browser you had been trying to do so with had failed, then
the replies could have been more crafted to answer your
real question. Most unaided .exc file types are generally
Windows and an exc is also used as a command file to
execute something; so even a savvy windows user may
decide to be careful in opening up and running an .exe file.
(They, like many kinds of file names for Windows could be
capable of harboring something malicious or unexpected.)
{Many of the file-sharing sites where people traded or gave
away, or shared music had made the news several times a
year; since there had been questions of legality in how some
of the music was shared. So, while there may be Mac-ready
sites where music could be downloaded for free, you have
to be aware that some of them may be operating outside of
the normal legally responsible channels. In other words, if
you randomly download stuff and don't care to know if you
have any rights to the content, you may be breaking a law.}
If you just want to listen to internet music content, on the other
hand, several stations across the world have channels online
you can listen to on your computer. Commercials, too; maybe.
And if you check the iTunes Radio, you can see a list of types
of music with a triangle by each one, click on those and see
the available station identities there, and double-click to be
able to see if you can get the station to work. Some just do &
some may not at different times. That works for free, but they
don't download to your computer. They just play like radio.
Although not recommended, there had been some software
that worked in demo or free (download) which could record
any sound in your computer; so such software could make
a recording of your computer's clicks, pops and any audio
which happened to be playing at the time you had the app
running. Including a sometimes very bad copy of music.
That ^ may be considered illegal, too; so that is a matter of
ones use of the rest of the internet to learn about this matter.
Anyway, there is a protocol and means toward an end, and
sometimes this requires a bit of effort to glean knowledge;
even if it is something you do not want to hear.
So, if you don't find answers to your liking, revise how you
propose the question and remember, we don't have to reply.
Not like the computer users sitting at home with a few hours
a week, knowing this stuff, are on the staff. We aren't.
Good luck & happy computing! 🙂
