Multiclip edit.
Or, if you don't have sufficient footage to do a full out Multiclip edit, and all the shots are timed together, stack all the video on tracks above each other, then shrink them all and move them around the Canvas window so you can see them all at once. For example, of you have four clips stacked, make them all 25% and move them to corners. then go and cut out what you don't want. When done, set the first clip back to 100% size, highlight it, copy, then select all, Paste Attributes, Basic Motion, and poof, they're all back to full size.
If the shots are not all timed together, then it doesn't matter, just do a regular edit like you would any other project. Lay your music track down, open clips into the Viewer window, set in and out points, overwrite edit, and work on down the Timeline to the music, cutting to the music beats and events.
Denisse, great video! Looks awesome! Just wish I could "hear" the music! For some strange reason I can't figure out, a couple of weeks ago, Flash videos and some .mpg's stopped playing their sound on my Mac. Both in Firefox, Safari, and even when I just download the files. Files I already have that used to have sound, now don't, also. Very strange, wish I could figure this out. But, the video looks very, very well editing, even without sound. Is there a way I could download a QT version of this video?
