How do i make the same song have two different genre

Question

how do i make the same song have 2 different genre for 2 different playlist?

Answer 1

In my example, we will create a Smart Playlist that includes all songs in the genre Acid Jazz and one extra song that has the genre of Afro-beat. That extra song will be "Music For Gong Gong". To create your Smart Playlist, substitute the genre types and the song title (anything with <  > around it) for the ones you want.
In your iTunes Library, either click on the + symbol in the lower left corner of iTunes playlists, or click CTRL+ALT+N to create a New Smart Playlist. The following will appear (my orange numbering):
1. Using the drop-down menus, change "Artist" to Genre, "contains" to is and in the text box (marked 1) type in the text <Acid Jazz> (remember to chose the genre you want, and with the exact spelling used for that genre in your library - don't type in the <  > obviously!)
2. Click on the + symbol at the end of that line (marked 2), which creates an additional line
3. In this new line, change "Artist" to Grouping, change "contains" to is and in the text box type in <Acid Jazz> (Notice that I have used the same name as the genre itself. You don''t have to, but it makes it easier to add those extra songs. You'll understand why in step 7.) You now have a box like this:
4. Change the Match rule at the top (notice it has already changed in the two screenshots above) to any. This is a crucial step, do not forget it.
5. Notice that I have also selected Match only ticked items. This is optional, but selecting it will exclude songs that have been unticked. If you use Sync only ticked songs and videos, this can be useful way of keeping the Playlist the same as the one on your device.
6. Click the OK button. You now have the opportunity to name your Playlist. I have chosen <Genre is Acid Jazz +> so that it is obvious what it is.
So that's the Playlist created. As you can see, <Genre is Acid Jazz +> has 89 songs in it and I can assure you that's how many songs are in the Acid Jazz genre section. Now, all that remains is to add the additional song.
7. Find your "two-genre" song and click File/Get Info/Info (or CTRL+I - that's an "eye") to bring up the edit song option. In the Grouping field, type in <Acid Jazz> (remember to use the same text you used in the Grouping box in step 3. This means you only have to type in the same genre name to the Grouping box,  to get it into that particular Playlist. I mentioned this in step 3).
Notice that we are not changing the Genre. Click the OK button.
Now look at the Playlist <Genre is Acid Jazz +> again.
Notice that is now has 90 songs and at number 60 is the <Music For Gong Gong>. Note that the genre for that song is still Afro-beat, so the song still appears in the genre Afro-beat as well.
To add any other song to this particular two-genre Playlist, simply find the song in your Library and type <Acid Jazz> into the Grouping box, as in step 7. It's that simple!
Here's an extra tip. Too many Playlists and having issues finding your way through them?
I have renamed the Playlist Genre is Acid Jazz + so that it is now named Acid Jazz Plus and I've dropped it into a Playlists Folder named GENRES (capitals makes it easy to find the folders on iDevices).
Notice that here in iTunes, Playlists are sorted in the following order:
Playlist Folders (and then the Smart Playlists and Regular Playlists inside it)
Smart Playlists
Regular Playlists
... but on my iPod Classic (for example), they are sorted in alphabetical order. So to find the Playlist Acid Jazz Plus, go into the Playlists menu and scroll down to G, go into GENRES, and in there will be Acid Jazz Plus, with all 90 songs!
I hope you will give this a try, you have nothing to lose but a little time. Let us (all) know how you get on with it. We'd like to know.
