this is 'time to pretend' by MGMT:

    standard tuning-
    e
    B
    G
    D
    A
    E

Intro:
  (sound FX)
       e|-------------|
       B|-------------|
       G|-------------|
       D|-------------|
       A|-------------|
       E|-------------|


        (intro riff)
          guitar 1 (maybe keyboard)

       e|-------------------|-------------------|
       B|--10---10---10---10|---8---7---8---10--|
       G|7----7----7----7---|-7---7---7---7-----|   x4
       D|-------------------|-------------------|
       A|-------------------|-------------------|
       E|-------------------|-------------------|

          i also like playing it like this (although its not fully correct
          it sounds more filling and cool):
       e|------------------------|---------------------------|
       B|-------10----------10---|-------10----------10------|
       G|----11----11----11----11|----12----12----12----12---|
       D|-12----------12---------|-12----------12------------|
       A|------------------------|---------------------------|
       E|------------------------|---------------------------|


          guitar 1 repeats 4 times, on the 2nd
          time this riff joins in:

           (main riff)

       e|-12-10-9-------14-14----|
       B|---------12-10----------|
       G|------------------------|    x5
       D|------------------------|
       A|------------------------|
       E|------------------------|


the above riff is played 5 times with guitar 1 behind it.
for the second last note of the above riff a D chord is played behind the note on the 
and 3rd time the riff is played:

       e|--------------|
       B|--------------|
       G|----7---------|
       D|----7---------|
       A|----5---------|
       E|--------------|
            (clean channel)

on the fifth time of the main riff the 14 on the e string is only played once, these are 
chords that join in with the heavy fuzz box (or synth.).

       e|---|-------|--------|--------|--------|
       B|---|-------|--------|--------|--------|
       G|-7-|---12--|---7----|---7----|---7----| X4 (FROM A G)
       D|-7-|-7-12--|-7-7----|-7-7----|-7-7----|
       A|-5-|-7-10--|-7-5----|-7-5----|-7-5----|
       E|---|-5-----|-5------|-5------|-5------|
          D   A G      A D      A D      A D


on the 2nd time through these chords on the
last A D the lead fills join in:

       e|--17--|-17--19--|--14--|--14--|
       B|------|---------|------|------|
       G|------|---------|------|------| X3
       D|------|---------|------|------|
       A|------|---------|------|------|
       E|------|---------|------|------|


ON THE FIFTH TIME OF THE CHORDS, WHEN IT GETS TO THE LAST A D INSTEAD OF PLAYING IT IT 
TO G ON THE 3RD FRET FOR 4 BARS

       e|----|---|---|---|
       B|----|---|---|---|
       G|--12|-12|-12|-12|
       D|--12|-12|-12|-12|
       A|--10|-10|-10|-10|
       E|----|---|---|---|
           G   G    G  G

the lead fill behind the chords:
       e|--17--|--17--|--17--|--17--19--|--14--|--14--|
       B|------|------|------|----------|------|------|
       G|------|------|------|----------|------|------|
       D|------|------|------|----------|------|------|
       A|------|------|------|----------|------|------|
       E|------|------|------|----------|------|------|


straight after the 4 bars it jumps straight back to the first set of chords BUT instead 
playing the A G it goes from D to the A Ds.
after the last A D it goes back to the Gs (whole thing repeats 2x).

after the last time it goes to like a bridge:
      e|----|----|----|----|
      B|----|----|----|----|
      G|-14-|-14-|-11-|-12-|
      D|-14-|-14-|-11-|-12-|
      A|-12-|-12-|-9--|-10-|
      E|----|----|----|----|

then pretty much goes to the start of the song again (main riff) except for the chords:
      e|----|-----|
      B|----|-----|
      G|-7--|-----|x4
      D|-7--|--5--|
      A|-5--|--5--|
      E|----|--3--|

with the main riff behind it for nine times BUT on the 9th time only play the 14 on the 
string once.

a little pause with sound FX and singing.
then the intro riff starts up for 8x with these chords behind it:

     e|------|------||-------|------|------|------|
     B|------|------||-------|------|------|------|
     G|---7--|---7--||---12--|---7--|---7--|---7--|x3 (from A G)
     D|-7-7--|-7-7--||-7-12--|-7-7--|-7-7--|-7-7--|
     A|-7-5--|-7-5--||-7-10--|-7-5--|-7-5--|-7-5--|
     E|-5----|-5----||-5-----|-5----|-5----|-5----|
        A D    A D    A G     A D    A D    A D

after 5 times of the main riff this riff comes back on:

       e|--17--|-17--19--|--14--|--14--|
       B|------|---------|------|------|
       G|------|---------|------|------| X2
       D|------|---------|------|------|
       A|------|---------|------|------|
       E|------|---------|------|------|

 then this riff with the bunch of Gs

       e|--17--|--17--|--17--|--17--19--|--14--|--14--|
       B|------|------|------|----------|------|------|
       G|------|------|------|----------|------|------|x2
       D|------|------|------|----------|------|------|
       A|------|------|------|----------|------|------|
       E|------|------|------|----------|------|------|

pretty much from then on it repeats from the bridge.
