Music time input

Thought it would be somewhat useful to use eases with sound behaviors.
For example, your game has a fast forward, and you want the music to also go faster.
Another, you could rewind the sound using eases reverse feature.
Or skip to part of a song you want at that time.
Another use was having things sync to a certain part of the song, so when the ease hits 5 seconds in, the song plays horns, and you could have an animation to match the part of the song.


I have also pondered this feature before, and I agree that it would make a lot of rythm or just audio based games so much better. One major issue is that I believe sound files are not loaded in until played, hence the delay when you first play a sound in an instance. This would have to be fixed in order for audio output to work with any sort of consistency.
