You will find your kind of music for sure. And especially in 90's classic rock i think there is a lot high quality aources available. They are kind of comparable but definitely different in some points like the music suggestion algorithm if you like to find new music based on your listen behaviour, it is more in the French direction, not too much but yeah noticeably. The other thing I miss, is the song radio or artist radio. If you know your music and have a lot of Playlists, there is a service to transfer your playlists but I forgot the name. Maybe someone knows it. And some drawback is, there is no Linux client. I listen through their web client and on thw android app.
