DRM (Digital Rights Management) is the method used by Apple to protect iTunes songs. This protection limits users from copying, sharing, or transferring their music files to other devices, leaving them locked to one device. However, there are still some things you can do with DRM-protected iTunes songs.

One option is to convert the files to an unprotected format. With the help of third-party software, you can convert DRM-protected iTunes songs to MP3 or other audio formats, allowing you to play them on any device you choose. However, this method is not legal and can be expensive.

Another option is to use the iCloud Music Library. By subscribing to Apple Music, you can store your DRM-protected iTunes songs on the iCloud Music Library, which makes it available on all devices linked to your account. However, there is a downside to this option as you need to pay a monthly subscription to use it.

You can also share DRM-protected iTunes songs with friends and family. While you cannot copy or transfer the original files, you can use Home Sharing to play them on other devices connected to the same iTunes account. This way, you can share your music with others without violating any copyright laws.

Lastly, you can simply continue to enjoy your DRM-protected iTunes songs on your original device. Though you may not be able to share or transfer them to other devices, you can still listen to them on your computer or mobile device.

In conclusion, while the DRM protection on iTunes songs limits their use, there are still some things that you can do with them. You can convert them to unprotected formats, use the iCloud Music Library, share them with family and friends, or simply enjoy them on your original device. Remember to respect copyright laws in all your activities with DRM-protected songs
