I found a phone in the street

So i was walking and i found a phone that was unlocked (with a code) and i found what that code was, the phone didn't have anything like "This is from me and me", it didn't have a Whatssap or a Discord for example, the galery was empty and when i searched the files of the phone i found that this guy who lost it was a huge Kanye West fan, he had like all of his songs and some unreleased (Like mama's boyfriend or see me again), so i keep the phone for music now until someone asks for it...
