Replaying a track can seem like standing still. In practice, the song has not changed but the listener has. The first pass makes a map: where the melody returns, where the rhythm opens, where somebody makes an unexpected choice.
On the next pass, choose just one thread. Follow the drummer through the bridge or listen for the pianist when another player takes the lead. Small decisions that felt incidental begin to sound like a conversation. A familiar tune can suddenly contain a new route through it.
There is no prize for hearing everything at once. Repetition is useful because it lets attention become more specific without making listening feel like homework.
