I wanted to learn DYLANs "it's all over now Baby Blue", there's part of the track where he just plays the harp on it's own, it was that part I was after. The easiest way was to rip it off a CD, then use a free audio file editor such as WAVEPAD to edit the song. It's easy, just cut the Harp section out & save it on it's own, giving it a name. Once you've saved it, you can load it back into WinMedia player(loads real quick 'cause it'll be a small file), set the player option to LOOP & just keep tryin' to match the timing/notes for as long as you like.
You could build up a complete library of riffs, song parts, etc, it's always just a click away & you've no need to listen to the full track, waiting for the section your interested in.
Works for me & it doesn't cost you anything, if your reading this then you have the tools
