Theres this one song I like - Time - https://www.youtube.com/watch?v=0qPZl7M2REM

If you change the speed to custom 1.05x and listen, you'll notice it sounds different to normal. Then if you switch to normal and listen again you can get your brain to recognise the different pitch from the 1.05x speed version and one time I got into an altered state of consciousness.
