Can the structure of a song be built up of just basic chords repated (like mine are), not including solos and bridges, or do normal songs have more technical strucutere to them?

nope most songs these days are formed off basic chords be it normal (eg maj and min) or power chords.

Yes i said MOST people, no reason to get all worked up and give me thousands of examples of songs that don't follow that EXACT structure.
