You can listen to to the music track while doing other things. Having it playing in the background.

If your bedroom is the only room you spend the bulk of the time use your activation cards there. You can also use it in other rooms in your house that are meaningful to you. Like computer room or lounge room. Even though you may not spend 5 hours there each time you go through the room it has meaning to you.

If all else seems impossible carry the intent. If you find yourself meditating in different rooms orient yourself in that direction (mentally or physically) And hold your activation card. I found it one of the more useful techniques than sticking it on the wall to be holding the card after reading it before starting the meditation.
