Literally nothing beats [url=http://www.youtube.com/watch?v=80l6tvxTpTI]Lucky Star's intro.[/url] [url=http://www.youtube.com/watch?v=Nb4bcmTOLjw] The Clannad version is even better.[/url]
On that note, [url=http://www.youtube.com/watch?v=pynkwIJrFEw]Clannad's[/url] and [url=http://www.youtube.com/watch?v=klUfRsd20gE]Clannad: After Story's[/url] intros are also amazing.
Code Geass also had some good openings. [url=http://www.youtube.com/watch?v=wLq1uhHTxl0]This one is my favourite.[/url]
Even before I started watching anime, I always thought their openings were catchy.
