I've been playing some simple strum along songs recently, and whilst I can get the chords and time the transitions right, I have difficulty in getting it exactly as written on tab. So what I get is the main sound of the song, but I'll probably get the syncopation slightly wrong. Its the rhythm thats the problem; what I play sounds alright but missing out the syncopated rhythms etc means I lose some of the songs feel.

Any suggestions on how I can improve my rhythm? Should I forget the tab and just try listening to the track and doing it all by ear?
