Just start the player as would you do normally, but add an ampersand at the end of the command, like this:
Code:
mplayer *.ogg &

Actually that will not work as mplayer reads from standard in and writes to standard out and error. When running mplayer in the background as suggested above, you will get a message:
Code:
[1]+  Stopped                mplayer *.ogg
Which means that mplayer halts until it can get access to the in/out file descriptors. typing fg will restart mplayer, but it will run in the foreground. You can avoid this problem by redirection in/out to null.
Code:
mplayer *.ogg </dev/null >/dev/null 2>&1 &

Thanks for the correction, I just assumed that you can send mplayer to background like you do with most other commandline programs. Good to know that doesn't work, and also how the command should look like.
