The playback speed of the song right now, seems at least 50% faster than it did when I was listening to it while walking earlier. Before it sounded like it could use a speed up, and now it feels extremely up beat....What is the scientific explanation for this? Is there one? ...Thanks

YES. I know totally what you mean. You see, just like vision, but more so, hearing is one of the senses that is very, very subjective. You don't realise it until, you hear different sounds at different times of the day and with different feelings. Here's a few points. I spent an intense year around 2003-2004 trying to produce dance music in the genre of "uplifting dutch trance" (no it's not a mixtape of a trip to amsterdam)... http://forums.di.fm/showthread.php?t=55556
1. It is well known that your ears are much fresher in the morning. Take some very high quality tracks with high quality earphones. Listen when you just wake up, a few hours after you wake up, then listen at night. You will notice more things earlier in the day.
2a. Music tempo is really a very abstract concept. That's why big symphonies have a conductor. When learning classical piano, yeah, you have a metronome, but during performances or when impressing your family, you don't use the metronome, and somehow the human mind tries to "keep" a tempo of the notes.
2b. A good example is the "beats per minute" a modern DJ uses. Even from vinyl to digital there's always been one main weapon in a good club DJ's arsenal: the RPM (or more relevant, the BPM[Beats Per Minute])... A song is created at a specific tempo (which can vary within a song), yet the DJ is at liberty to play it at whatever tempo he desires, within the range provided to him by his equipment. Roughly for dance music this is 120bpm to 140+bpm, with "hardcore" or "gabba" (not sure about the specifics because I'm not into these genres) running much higher, giving you the feeling like your head is going to explode. Of course, the DJ has to "tune" the BPM to the mood of the crowd. If they're pretty docile, you'd want to warm them up with some smooth but encouraging low-BPM stuff, then gradually increase it. If the crowd is already pretty jazzed you'd want to go in fairly jazzed up.
3a. Same with pitch. This is why many bands, symphonies, etc. spend hours, days, preparing at a venue and before each performance. Tuning is very important. Maybe some of you do know, but I only discovered, Linkin Park plays "out of tune" to some degree a lot of the time: http://www.guitarforbeginners.com/fo...drop-d-tuning/
3b. Some of you may know this, but do you realise that there are many "notes" between the 12 semitones? It's called tuning by cents: http://en.wikipedia.org/wiki/Cent_%28music%29
) ... Many bands and producers create different "signature sound and feels" by slightly tuning their pitch lower or higher, meaning they never play exactly an A Minor, for example, it would be tuned somewhere in-between an A Minor and A Major... From a piano theory point of view, guitar-wise I'm not sure if I understand this properly yet, see point 3a above.
4. Humans instinctively have some sense of the "mathematics in art". ... However this is dependent on perception, which varies from individual and even varies within an individual. For example, http://www.5cense.com/Edge_Delay.htm
5. Scientifically, it comes down to the brain/ mind. One of the important frontiers of knowledge. IMHO.
