Question: What is the best platform for streaming music?
Position‹2 of 5›: Soundcloud is the best streaming service
Argument‹4 of 4: Soundcloud is the best music streaming service because for discovering new artists

A lot of popular artists made their debuts on SoundCloud. SoundCloud still has this grassroots reputation. Dig around a little bit, and you can find brilliant artists who haven't been discovered yet.

The argument

SoundCloud is a great music platform to discover creative music and the artists behind the music. Popular artists such as Post Malone, Bryson Tiller, Kehlani, and Kygo were discovered on SoundCloud and are currently very "big" in the music industry. Their music was discovered before it was ever on Spotify or iTunes, which makes SoundCloud a place where many artists are and could be born. Everyone is invited to SoundCloud.

Premises

[P1]SoundCloud is where many now-major artists—Post Malone, Bryson Tiller, Kehlani, Kygo—were first discovered, before their music ever reached Spotify or iTunes. [P2] By being open to everyone, it serves as a launchpad where new and creative artists can be found and effectively born. [C] SoundCloud is the best streaming service because it is the best place for discovering new artists.

Counter-arguments

If someone isn't in SoundCloud's music "niche," it might be difficult to gain traction as a new artist. SoundCloud has already established its type of streaming music, whereas Spotify or Apple Music includes all genres and styles of music.

Rejecting the premises

[Rejecting P1] The artists named show that discovery on SoundCloud has happened, not that it happens there better than elsewhere: they are a handful of successes selected after the fact, and the same case could be built from breakout acts on any large platform. [Rejecting P2] Open access cuts both ways, since a catalogue anyone can upload to is correspondingly harder to search, and the argument says nothing about the tools that actually govern discovery — so being a place where artists are "born" does not establish that it is the best service for listeners trying to find them.
