Research for my Title Sequence

I used the website http://www.watchthetitles.com/tags/item/Documentary  to research on animated title sequences, and I found at least 4 good examples which are:

I like this title sequence because I really like the font used in it and the transition used in it gives a mysterious vibe. The music matches the whole video and it really catches my attention. This gives me a good idea for our original title sequence.

The transition in this video is really cool and I feel that the effects used are really 'unique' and it's something I haven't seen before. I might use some of the effects used for our title sequence.

This video is really mysterious and calm at the same time. The music really matches the videos, and it gives me a brief explanation on how to use the music and match the video. 

I like the music in this video and the text fading in and out really brings all the pictures, music and images together.
