Hey TaylorSwiftYAY,
The name leads me to believe you are trying to play her songs. I had to learn quite a few for my daughter to sing, anyway what you need to learn is boom chick strumming.

There is alot of this used in her songs, and after that learn to play single notes on the chords. It's actually a forward roll, while holding the position of the chord. Start with this and you'll be on your way to figuring out what makes up those songs.

One other thing I want to mention, you said you get chords off of other websites. I think you should be aware that most of that stuff is submitted by listeners, and singers. It is not put up bythe artist, so it's not always accurate. A singer would post it in the key they sing it in, and it may not be the key the artist plays it in.

Let us know how it goes, and have a great weekend.
