## Priority: Medium
## Description
`lib/music_library/scrobble_activity.ex:70,80,89``Enum.find` results are piped directly into `Release.medium_duration/1` without nil guards. If a medium with the specified number isn't found, this crashes with a `FunctionClauseError`.
## Expected behavior
Add nil guards or handle the case where `Enum.find` returns `nil` gracefully.
## Source
From technical debt audit (2026-02-17), item #3.
