1) Having to load 5 secs of the next song just in case the user wants to
skip it wastes buffer space.
2) The mp3 buffer algorithm would be more complex, as it would have to skip
the prefetched data if the user doesn't press next.
3) The extra directory lookup, seeking, ID3 parsing and bit swapping would
probably take extra time, and would force us to use a higher watermark
level, decreasing the buffer usage and increasing the battery usage.
4) The track change detection algorithm would be more complex as well.
