Here's the signature riff of the song (play it FAST!): E-|-----------------|-----------------|-4---------------|---------4---------| B-|-7---5---5-7-----|-7-----5---7-----|-5-5-------------|---------5---------| G-|-7---7---7-7-----|-7-----7---7-----|---4-4-------4---|-4-4-4-----4-------| D-|-7-7---7-----7-7-|---7-7---7---7-6-|-----6-6-----4---|-4-4-6-------6-----| A-|-----------------|-----------------|-------7-7-7---7-|-------7-------7\5-| D-|-----------------|-----------------|-----------------|-------------------| E-|-2---------------|-----------------|-----------------|---------------2-2/| B-|-3---------------|---------3-------|-3p2-----------3-|-3-2-2-----2-2-3-3/| G-|---2---------2---|-2-2-------2-----|----------2----2-|-2-2-2-----2-2-2-2/| D-|-----4-4-----2---|-2-4---------4---|------2-----2--4-|-4-2-2-2-2-2-2-0-0-| A-|-------5-5-5---5-|------5--------5-|-----------------|---0-0-2-2-0-0-0-0-| D-|-----------------|-----------------|-----------------|-------2-2-----0-0-| Repeat 3x; then...

One time with the first ending that I've tabbed out (marked between the 1>>>> and <<<<1), and again but replacing the first ending with the second (2>>>> to <<<<2). This is also the part played behind the chorus ("Always one more; you're never satisfied..."): E-|-2------|-------2-2-----4-|-4-----------|-------4-4-----2-|-2--------------| B-|-3------|-------3-3-----5-|-5-----------|-------5-5-----3-|-3--------------| G-|-2------|-------2-2-----4-|-4-----------|-------4-4-----2-|-2--------------| D-|-0------|-------0-0-------|-------------|-------6-6-----4-|-4--------------| A-|-0--0-0-|-0-0-0-----0-0---|----0--0-0-0-|-0-0-0-----0-0---|-----0--0-0-0---| D-|-0------|-----------------|-------------|-----------------|----------------| E-|-(2)---------------|| B-|-(3)-------3-------|| G-|-(2)---------4-----|| D-|-(4)----/5-----5---|| A-|--0-0-0--0-------5-|| D-|-------------------|| 1>>>> <<<<1 E-||------------10-10--9--9--7--7--9--9-10-10|| B-||3p2------2/-10-10-10-10--9--9-10-10-10-10|| G-||----2----2/------------------------------|| D-||------2----------------------------------|| A-||-----------------------------------------|| D-||-----------------------------------------|| ^{Tab from: http://www.guitaretab.com/v/van-halen/20129.html} 2>>>> <<<<2 E-|-------------2|2-0-0-0-0--2-2--------|---------------|----|-----------|| B-|-3p2---------3|3-2-2-0-0--3-3------10|10-9-10-10\-2-2|----|-----------|| G-|-----2-2--2--2|2-2-2-1-1--2-2------11|11-9-11-11\-2-2|---2|-----------|| D-|-------2--2--4|4-2-2-2-2--0-0------12|12-9-12-12\-2-2|---2|-----------|| A-|-------0--0---|--0-0-2-2--0-0--0-0---|------------0-0|---0|-----5---3-|| D-|--------------|------0-0--0-0--0-0---|---------------|----|--/7---7---|| This next bit is played behind the verses. It's basically just crunching out a D power chord with the low D thrown in. Eddie does a little bit of extra stuff (which I tabbed out here) but you really don't need it unless you're really anal and want to be exact...

Play it twice through, only the second time, leave out the first measure (A-2-3-2-3-2-3/5). Then rake your pick down the low strings before you go into the next riff.

This is just a fill-in between the pre-chorus (above) and the chorus (WAY above). Play this one time through then go to the chorus riff (tabbed above).

Just arrange those basic riffs in order by listening to the song and you'll have the main structure (sans solo). The solo is more than I'm willing to attempt to play OR tab. Corrections/augmentations/comments welcome... Good luck!
