iTunes is exclusively Apple-based, If all your music files are downloaded from itunes plus, you can directly sync songs from itunes library to your HTC explorer Phone without problem

However, some iTunes downloaded songs has the DRM protection which avoid customer to transfer them to other incompatible devices(non-ipod device), so if you need to bypass drm first, 2 ways are as follows:

Burn songs on iTunes

1.Create an iTunes playlist containing the purchased DRM protected songs.

2.Insert a blank CD-R or a CD-RW into your computer's hard drive.

3. Burn the playlist to disk with iTunes.

4. Rip the burned CD to get DRM-free songs.

Another option would be to turn to software that automatically converts your iTunes purchases to MP3.
