You reach the later tracks with less attention than you gave the opening. That can happen even with music you like. Before deciding the second half has less to offer, give it a session of its own.
Use the release’s own division where possible
For a record with sides, begin with the side you tend to neglect. For another format, choose a sensible break and note that the division is your listening choice rather than part of the release.
Do not shuffle the tracks for this exercise. Keeping their order lets you hear the local sequence while changing where your attention begins.
Choose one question
Listen for the first major change, the track that alters the pace or the way the final section closes. A single question gives the session direction without making it feel like an inspection.
Write a brief note before comparing it with your memory of the whole album. You may find new interest, or you may still prefer the opening. Either result is useful if it becomes more specific.
Rejoin the halves
On a later day, play the album in full and notice the transition across your break. Combine the exercise with checking running orders when you own multiple editions. A change in listening conditions is not proof of a change in the record, but it can reveal where your earlier judgement came from.
