Amarok 1.4 was so good that I switched to linux for it, even bought a t-shirt. Amarok 2 was what made me leave. I've toyed a bit with quodlibet and clementine, but for me 1.4 was the peak music player.
To be honest I wasn't on Linux yet during 1.4 ( had a quick look to Wikipedia )
So I guess I tried it for the first time when it was already in 2.0
The logo is so nice tho, no wonder buying a t-shirt look justified ahah
It was so good that it was the first project i gave some money, then they killed the database connection...i was pretty angry at them, never used it since then.
