Soulja Boy Says Concertgoers Need To Stay Vigilant After Astroworld

Soulja Boy says fans should be more aware of their surroundings the next time they're at a crowded concert like Astroworld ... but it's also on organizers to create a safe environment.

We got the rapper in NYC on Thursday and asked him what artists are doing to prevent another deadly scene like the one we saw in Houston from happening again.

Soulja says it will take a collective effort to prevent another tragedy ... telling us it's also up to fans to enjoy themselves without getting too wild and making sure they know what's going on around them.

As you know ... the death toll from the Travis Scott show now stands at 9.

SB says people can get caught up in the concert, especially when they all have their phones out, and that's when bad things can happen.

But it's not just up to the fans ... Soulja says venues and promoters need to take the proper precautions for everyone's safety, no matter if it's looked at as an inconvenience. Interestingly, he did not mention the responsibility of the artist.
