Taylor Swift has been performing songs from other artists while on her Speak Now tour.  Her most recent cover was an acoustic version of Fall Out Boy's "Sugar We're Going Down" while performing a concert in Chicago.  Catch it after the jump.

Before performing the song she told the crowd that she listened to this song during her freshman year and the band was from Chicago.  Since she was playing Chicago, she asked the crowd to sing loudly along with her.

About 3 weeks ago Taylor performed a song from Bon Jovi and she has also covered Bruce Springsteen, Pink, TLC and Eminem in the past.

How do you feel about artists performing songs from other people -- is it ok or should they stick to their own material?

Here's Taylor performing Fall Out Boy's song and then I've got the original right after it!
