They say, "Imitation is the best form of flattery." It's common to hear a rapper claim other artists are copying from them, but there isn't always proof of this. It's also a common theme for critics to claim, "everybody today sounds the same." Claims can be vague, circumstantial, or even just flat out wrong, but for the below artist there does seem to be some truth.
GUERILLA BLACK and NOTORIOUS B.I.G.
In 2004, local radio stations still held a sizable influence on how people heard new music. Without a visual many confused newcomer Guerilla Black with a new posthumous track from Notorious B.I.G. Even beyond a clear copy of cadence and voice inflection, the resemblance stretched to style and physical appearance. Though Black's music was on some level enjoyable most people didn't appreciate the similarities to a legend such as Biggie, and thus his career didn't go far.
ACTION BRONSON and GHOSTFACE KILLAH
From the start of his career many compared Action Bronson's flow to Wu-Tang Clan member Ghostface Killah. The comparison eventually evolved into a feud between the two in 2015. Bronson still retains a core following though, and recently debuted his own television show, "Fuck, That's Delecious!", on the Viceland channel.
ARIANA GRANDE and MARIAH CAREY
The only singer to make this list, Ariana Grande is a full on pop superstar at the moment. Usually, having a voice comparable to Mariah Carey would be the dream of most singers. Many have tried and failed, including Mariah herself these days, to hit those super high notes with extreme vocal precision the way Mariah iconic for. Luckily, Ariana is among the few who have succeeded. The comparisons don't end there either. Rumor is that Ariana could have some nasty diva antics in her as well, and there is no secret that Mariah can be difficult at times.
YOUNG CHRIS and JAY-Z
Now this one is interesting because there is debate on who influenced who. Basically, both artist on the same label used the same style while rhyming for a brief time period. According to Chris, the likeness came from the family atmosphere Roc-a-Fella Records had established at that time. He claims that in spending so much time together you tend to learn and pick up things from each other.
YOUNG DOLPH and 2 CHAINZ
The similarities lay in their style of rapping more so than the actual timing or cadence. Both are artistically simplistic in their lyrics managing to give rewind worthy lines without having to decipher much. The two also delivery a familiar sense of humor in their raps, often based upon blatant sarcasm. Combine that with their southern dialect and the resemblance is evident between the two.
YOUNG THUG and RICH HOMIE QUAN
Aside from tone, these artist are alike in numerous ways. From fashion and stage presence, to rhyme delivery and topics, to even the people they affiliate with. The two are currently at odds now, but even that feels like two brothers mad at each other more so than rappers beefing.
DESIIGNER and FUTURE
Of course this made the list. Similar to Guerilla Black's situation, without the visual many assumed the hit record "Panda" was yet another gift from Future. The barely audible lyrics, beat selection, and crazy ad libs are all synonymous with Future, but in fact this song belongs to new G.O.O.D. Music signee Desiigner.
