Hi Hollie,
Sorry you are frustrated with the way some of the music is formatted, as Alvee said, Chordie doesn't "make" any of the music on the site... just links users to others who have hosted them. Particularly in TAB and also in chords, the tunes are based on the contributers "best guess" of what sounds correct to their ear. It might be in a different key than the original recording and not sound right if you played along with the original artist's recording.... in which case you can try the transpose feature and adjust the chords to your voice or whatever.
Many songs will only have the chords annotated for the Intro, Verse, and Chorus, and then only the lyrics for the rest. It is assumed that all the verses will have the same chords and so you simply play the chords from the first verse for each successive verse and the same goes for the chorus, If the piece has a bridge, then usually that will also be specifically scored further down the page where appropriate.
Don't give up on it, it is likely not "laziness" just redundancy. We are thankful that someone even "bothered" to try to figure out the tune in the first place, and you will usually find a notation on the music that allows you to contact the "Tabber" directly to submit suggestions or corrections so that all may benefit from the most accurate version that you don't have to pay $$$ to some publisher for.
Thanks for posting your question and
Take Care;
Doug
