I believe this problem was caused by the Media Scanner program getting hung on a bad media file and restarting repeatedly. This resulted in the device not going to sleep and no music files being indexed. I resolved the problem by putting ".nomedia" files in all of my media directories (music, photos, video), and removing them one by one to see which was causing the problem. In my particular case, it was a picture, so I narrowed it down by using the Gallery app. Before, the Gallery app would appear to be constantly looking for new pictures/video and would be unresponsive at times. After resolving the issue, the Gallery app quickly finishes looking for new media and is very responsive. I also have all of my music indexed now.
