He can rap (Duh), he can produce (see: all of his beats), and apparently he can sing (Love Lockdown, & Heartless)

1st: there were the "Flashing Lights" video(s)
2nd: Love Lockdown
3rd: Heartless
* Are you seeing the pattern: Innovation; a constantly evolving sound; refreshing genre jumping.

I preface this song no further:

- Listen

- React

- Love

Kanye West - Heartless
