If you visit Everypony Sings regularly, you've probably seen WeimTime007's great visualizations/synesthesia videos. Well, he's back with two versions of the Title Theme, and they're both well done.
Embedded is his visualization of a solo piano version of the Intro. It was transcribed by whyPon and configured by WeimTime007. There's also sheet music to go with this version.
The other version is a full instrumentation of the Intro, which you can find here. Again, whyPon and WeimTime007 collaborated to make this video happen. Well done!
