Yes, all beginners have problems with making a song sound like it "Should". I still find it takes a long while learning from tab,but if somone shows me the riff - i get it quickly.

If you can afford it i recommend you find a teacher, I had 6 or 7 lessons when i had been playing ten years and it made me a lot better.

An easy song is A Horse With No Name [only just found out how easy it is].

This is a great page for beginners

Good Luck.
