AM
- it syncs with everything
- easy to find music
- mobile experience is the best of the three
- connect
- beats1 radio shows are actually good
- forced to use it with desktop iTunes which is terrible.

Tidal
- hifi is legit hifi
- owned by black people
- unintuitive interface

Spotify was first but its really only good with the desktop app...and they have a free option. Ive stopped using it since AM came out. I like my music in one spot.

Spotify

- Can check on my friends music as well

tidal

pros:
hifi
sleek and easy user interface
great exclusives

cons:
i'm using it because i bought a $20 subscription by accident

Spotify as my dad pays for Premium.

I use Tidal free trial for Beyoncé's music because the quality is truly amazing.

Cons:
Shuffle on Mobile App
Can't move app to Micro SD
No Taylor Swift

Pros:
Free

As of lately they have added a lot of artists under LOEN Ent. (Oh My Girl, Fiestar, Seventeen )
They are just lacking JYP (Even tho i only use TWICE and Got7)
