I dont know about anyone else.
But I'd say the three of you have a band
You "ring"
Try Nobody Cares as either a trio or with a female singer
Your voice just doesnt seem to fit that one well. No offence
Same thing with the chorus portion of Give it up. ( trio)
You seem to be reaching to hard for those higher notes
Or try singing more from the dyaphram and less from the back of your throat
the other stuff where you used multiple voices sounds great though.
May keep em myself
