Rhythmbox alphabetizes an artist or song title that begins with the word "the" under the letter "T." For instance, the group "The Decemberists" gets listed right next to "TeneciousD". Every music player I have used in windows, along with Songbird and Amarok would list "The Decemberists" under D. I really like rhythmbox but I find this little quirk to be very annoying and it is kind of a show stopper for me. There may be a plugin which changes this behavior, though I haven't found it...
