使用Applescript将BPM和星级评级复制到iTunes中的评论

我想要一个AppleScript来获取所选MP3组的BPM和星级，并将信息粘贴到评论部分。

我发现这个代码可以一次复制一个轨道的星级，但我不知道它足以修改它来做一组选定的轨道并抓住BPM。

tell application "iTunes"
    set theTrack to (item 1 of (get selection))
    set theRating to rating of theTrack
    if theRating = 100 then
        set comment of theTrack to "5 Star"
    else if theRating ≥ 80 then
        set comment of theTrack to "4 Star"
    else if theRating ≥ 60 then
        set comment of theTrack to "3 Star"
    else if theRating ≥ 40 then
        set comment of theTrack to "2 Star"
    else if theRating ≥ 20 then
        set comment of theTrack to "1 Star"
    else if theRating = 0 then
        set comment of theTrack to "0 Star"
    end if
end tell

您想要获取选择，这将是一个轨道列表。然后，使用重复块处理列表中的每个轨道。这是脚本。您可能希望添加检查以确保iTunes正在运行，并在发生故障时尝试阻止：

tell application "iTunes"
    set selectedTracks to selection
    repeat with thisTrack in selectedTracks
        set theRating to rating of thisTrack
        set theBPM to bpm of thisTrack
        set theComment to "" & (theRating / 20 as integer) & " star | BPM: " & theBPM
        set comment of thisTrack to theComment
    end repeat
end tell
