as long as you ain't breakin major bread you'll be cool. nobodies gonna sue you unless they can fill their pockets in the process. i know mad hiphop cats on indi labels, CEOs, presidents, etc. of indi's who don't clear shit. these cats put out CDs with no citations of any sample usage. shit atmosphere NEVER clears samples, though they've been sued multiple times... but them cats ain't hungry that's for damn sure.
