I want a command line to play a specific music file in terminal (or script) from my hard-disk. Is it possible without installing extra packages?
I think the default installation has no way to play audio files from command line, other than using aplay on WAV files (aplay also support other formats, but the man page is not clear in this regard).
To play, for example, MP3 files, you need restricted codecs available through ubuntu-restricted-extras, and a player like mplayer or cvlc, but there are many other: see What Media Players Are there? where text based and GUI based audio players are listed.
