This music can be broken in 2 parts, the one who ?akon sings and the other he play guitar.

First part : ?akon sings just two notes, D# and E, if you can sings those notes, you can 
sing the first part of this music(i don't know the lyrics, sorry).

Secons part ( guitar ) :

E|-------------------------|--------------------|

The rest it's just repeat, and the end of the song is B|-12-|

Some parts of this music are played with one octave below simultaneously or the next 
riff played at the same time ( i hope my english is understandable )

:)

Ps.: i'll tab the other songs if  possible.
