Who doesn't remember iTunes? I miss it. I always used it to listen to music when Spotify wasn't so popular. But why not merge iTunes with Spotify and YouTube, and give it my personal touch? The result was this: SharkWave.
It's still in development, it doesn't even have Spotify or YouTube built in, but you can try its local music player.
Simple, just make sure you have a folder called SharkWave
and it is organized like this:
~/SharkWave/
└── Artist/
└── Album/
├── song1.mp3
├── song2.wav
└── song3.flac
Make sure the music is in MP3, Flac or Wav format.
