Jessie J - Do It Like A Dude

The chords throughout the whole song are

   Dm   F   C   Dm (or any variant of those chords, they are the ones I use)

e|-----------------|
B|--6-------5---6--|
G|--7---2---5---7--|
D|--7---3---5---7--|
A|--5---3---3---5--|
E|------1----------|


Guitar riff

e|------------------------------------|
B|---66-66-6-66-66-6-55-55-5-33-33-3--|
G|----------5--5--5-5--5--5-3--3--3---|
D|--7--7--7---------------------------|
A|------------------------------------|
E|------------------------------------|

It pretty much is that throughout the whole song, the guitar riff drops out during the 
bridge and build up to the final chorus.
