I know we had discussion on music in fanfiction not too long ago but it irks me when writers try to force their musical tastes through the characters, especially if they don't fit. I really doubt Tali is going to have a thing for Led Zeppelin in the 23rd century. Call it that classical music of the time, it still feels forced.
Another related pet peeve is when characters make references to 20th-21st century media as if its still relevant in the future. No, Noble Six is not going to be making Total Recall references in the 26th century. At least not without most people raising an eyebrow. I don't know what movies, shows, or books are going to be like in the future, but making up references to those to balance out the modern stuff is vastly preferable.
