1st time user on Audacity 2.0.2

Using 2.0.2 for the first time - recording a sound-bite straight from youtube to playback at a party as someone’s ‘intro’.

When I audition the sound on youtube, it sounds full and rich. But when I record the excerpt then stop everything and then playback, it sounds tinny and weak.

What am I doing wrong?

It’s possible on some computers to record “what your computer is playing” internally and the presented sound and the recorded sound should be the same. It’s also possible to record your laptop’s microphone and speakers and that will sound pretty awful.
