If you're trying to do accurate note-for-note transcriptions: don't bite off more than you can chew initially. In some songs, different lines will be played every time through the chord progression. So you end up listening to the line over one chord, pausing, figuring it out, writing it down, listening to the next chord, pausing, figuring it out, writing it down, listening to the next chord, pausing... over and over. So you end up transcribing 16 individal measures and you've only done the first verse
You might be better off to start with a song that has a little more repetition to it. Then you can transcribe the line, listen and verify it's played the same later in the song, copy, adjust for the occasional different note, the use of an octave, a run, etc.
Starting off I think it would better to set a goal you know you can achieve and be proud of. Then move on to a more difficult song with a lot of variety.
That's just my 2 cents.
