From Deputy Doofy:
1) The big reply box should say “Leave A Comment” rather than reply. Why? There’s already a reply link under someone’s comment and may confuse people as to whether they’re replying to a person or “replying” to a song… the latter not really being a reply.
2) Play a song. While the song is playing, enter some stuff in the comment box. Use your arrow keys to move the cursor…. and the music player reacts also. The music player shouldn’t react to arrow keys if it doesn’t have focus.
