Lost: Not being a native English speaker, or not educated in written English, you have an excuse for confusing you're/your. What gets me is when educated native English speakers do it. Here is the difference:

"You're" is a contraction for "you are." Example, "You're excused for not knowing the difference."
"Your" is a possessive pronoun. Example, "I share a lot of your peeves."
Saying "ur" in place of either one of them is just illiterate, in my opinion.

Oh yes, bad cover songs. Even good cover songs can annoy me in some situations. For example, Dolly Parton wrote "I Will Always Love You" and has been performing it since 1974. It has been a hit song for her twice as a solo recording, and once as a duet with Vince Gill. So why, now that Whitney Houston has passed, is everyone acting as if that's "her" song? It often happens that way when one musician records a song and has success with it, but then a version done later by a more recognized name is a *monstrous* hit. As another example, Gary Morris won Song of the Year in two different country music award ceremonies in 1983 for "Wind Beneath My Wings." Now, any time he performs it, he hears, "Hey, I like the way you did that Bette Midler song." This happens despite the fact that her version came seven years later.

Why does that piss me off? I don't know. Maybe because I know what it's like to do something first, but then somebody else gets the recognition for it later.
