6.1 GB used, 75.4 MB left. Music takes up about 5 GB (742 songs), the rest is photos and other apps. I'd probably have thousands of songs on my phone if I had the space though.
Yeah that's why I don't download those types anymore. The space really adds up.
You could use a MP3 converter, I listen at the best quality when I'm at the PC but I don't mind lower bitrates on the phone as long as the quality drop is not noticeable by the ear. You can have more than double your song capacity.
