At Wikiloops, we have that concept of a ‘watchlist’, and mine got filled quite a lot recently. Each time I sit at work and listen to something where I think I could add something, I add it to this watchlist – so mine currently has over 100 gems inside:
At home, I’ll download all of these when I have the time, and start ‘working’ on them in my DAW (=’Digital Audio Workstation’). Convert MP3s to WAVs with Audacity first, then load them into Ardour. Set the tempo, check with a metronome, eventually make a clicktrack and/or a count-in. See if I can enhance the given audio, and it helps if you have single HD tracks because a drum kit or a guitar might need other treatments than a voice.
Often I also add markers where the chords change or to separate parts of the song so during recording I can see the structure.
And finally I’ll grab my bass and play.
And all of this is great fun. I’m learning so many different things. And I’m so glad that I found Wikiloops…
