remeber you can always take a song with open chords and change them to bar chords. understand that there are many diferent voicings for chords, basically how the notes are arranged. so instead of playin open c majour chord, play the a majour shape with the bar on the 3rd fret. or instead of playin open G, play the e maj chord shape with the bar on the third fret. or instead of D majour play the a majour shape with the bar on the fith fret.

u get the idea

hope this helps
