Sometimes I guess you just have take a chance. Chances are that if someone came to you with a carload of money the sampleclearance wouldn't really be a problem, cause that's just what the sample owner wants aswell...monaaaay...and with a carload I'm sure you could have spared some of it. After all, if the track isn't worth s*** without the sample, then sharing the money seems fair.
Now...I live in norway so the chances of someone showing up with a carload of money cause they like my stuff is rather slim...actually it's more likely that Britney will be bootycalling me than for that to happen. Which kinda makes me not care alot about the sample issue. If I use one and someone has a problem with it I'll kill the beat if that's the issue. There has been a couple of cases of that here in norway and it really didn't blow up all that much. As long as you don't make any money on the beat, it shouldn't be a problem.
Please excuse me...If you need me I'm sitting firmly beside my phone waiting for Brit...hehe
Also something worth thinking about: Is the sample really unique? and easily recognisable? If not it's even less of a problem.
