The melody of Champagne Supernova by Oasis runs 478 notes across 51 bars, 6:03 long in A at 78 beats per minute. The tab sits low on the neck, mostly under the fourth fret, one note at a time — no chords to barre and no strumming pattern to keep up with. A piano backing track plays the chords and bass underneath, so the line you are learning sounds like the record even at half speed.
