Song remixes that ruin the original.

I can appreciate a good remix.  But what annoys is when someone takes the song, adds 20 minutes of "wub", one line of the original, and calls it a remix.  I can't stand more than about 30 seconds of "wub" total for an entire song before I get annoyed.  Or when some rapper takes the beat from a track and gives no credit anywhere of where they got it.  I can't even think of an example.... my brain is dead right now.  Sorry for the short post.
