Lakers star Nick Young was pulled over in Hollywood last night -- after cops say he was bumping his music too loud in a rental car ... TMZ Sports has learned.
But during the stop, Young claims the cops took a cheap shot at the Lakers ... though, it's not like they lied.
Here's what we know ... cops say Young was going down the street playing his music too loud -- and didn't have license plates on the car.
He was pulled over by a police vehicle -- and we're told another unit that happened to be close by saw the stop and went over as backup.
