you can use

,--------------------------------------------------------------------------
| start-process is a built-in function in `C source code'.
| 
| (start-process NAME BUFFER PROGRAM &rest PROGRAM-ARGS)
| 
| Start a program in a subprocess.  Return the process object for it.
| NAME is name for process.  It is modified if necessary to make it unique.
| BUFFER is the buffer (or buffer name) to associate with the process.
| 
| Process output (both standard output and standard error streams) goes
| at end of BUFFER, unless you specify an output stream or filter
| function to handle the output.  BUFFER may also be nil, meaning that
| this process is not associated with any buffer.
`--------------------------------------------------------------------------

e.g. M-:

,--------------------------------------------------------------
| (start-process "mp" nil "mplayer"
|   "-playlist" "http://streams.greenhost.nl:8080/hardbop.m3u")
`--------------------------------------------------------------

and then M-:

,--------------------
| (kill-process "mp")
