The one that really used to bug me, both for grammar and lyrics, was the Thompson Twins's "King for a Day" (and now I'm really dating myself):

If I was king for just one day
I would give it all away
I would give it all away to be with you

So, besides the "was" issue, if you were king for just one day, why would you have to give it up to be with someone? It's only a day! They can go to the movies or something! And if you're king, why not have them there with you anyhow?

Clearly, I spent too much time thinking about this.
