Whitney â€`` who debuted tracks from her upcoming LP 'I Look To You' in London last week - said: ``It's great to be back, it's more like riding a horse. A bike you can stop, break. Sometimes you've got to pull the horse reins back, you've got to hold the rein a little betterâ€¦'' Whitney â€`` who has a 16-year-old daughter, Bobbi Kristina, with ex-husband Bobby Brown â€`` insists her style of music has changed because it represents everything she's been through. She said: ``I'm a lot wiser now, certainly a lot older. Things mean a lot more to me. I have a 16-year-old daughter, which makes a lot of changes in a woman's life. I think the songs themselves will speak to you when you hear them. And you'll understand where I am and the changes I've gone through for the better.`` In the past few years Whitney has battled serious drug addictions and gone through a bitter divorce battle.
