A lot of modern pop music sounds like AI to me due to the overuse and/or reliance on autotune.
Its all very well AI being able to approximate R&B (rapping & bullshỉt) artists like Drake or Areola Grande, but I doubt it will be able to do a convincing song in the style of Led Zeppelin yet.
Maybe AI will be able to 'unautotune' the vocals on the songs it makes, so we could potentially end up in the position where AI generated R&B (rapping & bullshỉt) songs will sound more human than a human in that style.
