I have the most of my music on 1tb+4tb+500gb External drives(seagate) & 99% of my files is in FLAC or ALAC, the rest in MP3 320kbps. So I mostly listening to that(over 250.000 Files). But I have a few Streaming Services also: Spotify Premium+Apple Music(Itunes & on Android)+Deezer Hi-Fi+Tidal Hi.Fi & Youtube Premium.
