My MacBook just "wakes" up with no apparent reason, or a any pattern I can point at, it's quite annoying especially when the battery runs low or when it happens in the middle of the night and wakes me up.
You should check your "Energy Saver Settings", and your "Bluetooth Settings" to see if there are external causes for its waking.
It also might help to change your "Energy Saver Settings" to "Better Energy Saving" while you're not actively using your Mac. At least that way it'll turn itself back off.

How can I wake my computer from sleep or
On most computers, you can resume working by pressing your
computer's power button. However, not all computers are the same. You might be
able to wake your computer by pressing any key on the keyboard, clicking a mouse
button, or opening the lid on a laptop. Check the documentation that came with
your computer or go to the manufacturer's website.

The hinge is a very fragile part of the Macbook. In the hinge goes all the video and sound cables, as well as the backlight power. You can have a hardware problem here with your connectors.
However the sleep mode can also take its time to wake up:
- The hard dive needs to wake its 5400 rpms
- The system has to wake
- The video has to wake
I would think that a fast internal hard drive, as a SSD drive for example, will wake up much faster.
Hope this helps
This can be caused by the audio jack, if it doesn't sit tight anymore, the headphone becomes disconnected for small periods of time causing the iPod to detect the headphone as unplugged, hence it will pause. Try different headphones, especially nickel plated ones and make sure there's a tight fit. If that doesn't help the jack needs replacement. If you're out of warranty you can send it to a third party iPod Repair Service.
