I know really well and like a lot the following ones (specially love the red ones)

Tchaikovsky (182)
Mahler (145)
Bruckner (100)
Schubert (97) very charming but don't love all of it (I don't consider it a Mozart pastiche either)
Sibelius (97)
Shostakovich (95)
Prokofiev (70)
Nielsen (43)
Mendelssohn (15)

I have listened to these but don't know them as well as the above ones:

Vaughan Williams (31)
Dvořák (27)
Arnold (7)

I might explore these:

Martinů (10)
Honegger (9)
Schuman (4)
