In Windows my dad used to have a program called MP3 Tunes. I have tried running it with Wine, and it worked. But strange things kept happening to the program, so it's not a reliable way to play music.

Basically I just want to have 2 players (in a single window) with these features:

• Preloading tracks in a player without immediately starting them.
• Fading from one track to the other.
• A timer on each player.

These features are also desired, but not required:

• Microphone input.
• Prelistening before loading a song in a player (through a seperate sound card).
• Pitch/Tempo control.
• Just being able to browse folders in the filesystem (without things like a music library).

Here are some screenshots of the program to clarify what I'm looking for:
