Drake-Lamar beef is bewildering

Full disclosure, I'm not a huge fan of either Drake or Kendrick Lamar (or of rap in general, tbh). But I'm still a bit bemused by all the fuss over this ongoing "beef" between them, which became even more public after Lamar's star billing at this year's Super Bowl and his performance of the song Not Like Us.

Probably the two biggest rap stars in the world right now, they have been "dissing" each other for years now, but it came to a head with Lamar's allegations (originally veiled, later fully-realized) that Drake has had sexual relations with underage fans, and maybe even has a young girlfriend hidden away somewhere. 

"Say, Drake, I hear you like 'em young ... Tryna strike a chord and I hear it's A Minor ... Certified Lover Boy? Certified pedophile". It doesn't get much more in-your-face than that!

Drake has responded with his own diss tracks against Lamar, and most recently by suing Lamar's record label for releasing Not Like Us, which of course has only met with ridicule from the macho hip-hop crowd.

But hold on, what evidence has Lamar for his allegations, in verse and otherwise? Drake has challenged him to reveal his proof, to no avail. I've read several articles on the subject, and nowhere have I seen any kind of proof being offered. Maybe it has to go to court before such minor details need to be addressed?

It's not clear to me exactly what you can say in a song, and avoid being accused of slander and libel. But surely you can't go around accusing people of being pedophiles and expect to get away with it? Can you?

It seems to me that this whole diss thing is just a way of selling more music and making more money (not that either of them need it!) Not Like Us saw a 430% increase in streams after the Super Bowl half-time show, reaching a billion streams on Spotify alone.

There are also allegations (also as yet unproven) that Lamar's song streams, particularly of Not Like Us, have been artificially inflated by the likes of Spotify and Universal Music Group. The whole thing looks very sordid.  Maybe they just have nothing better to do than exercise their inflated egos.
