Audio Share the music player/music effects app you use

Hey guys
I made this thread so we can share the music player and/or music effect applications we use so others can know about them too.
We have WALKMAN™ as our stock music player (and its pretty cool) and Sound Enhancements for audio effects. But there are loads of other good music players and audio effect mangers out there too. If you know any good ones, share them here so we know about them as well

I found a music player (Windows Phone based) ZPlayer which has a really cool and minimal UI (free version here). And I use ViPER4Android for music effects. Any other good music player/sound effect app you know about?

Some screens from ZPlayer:
