When ringtones first became available I checked my music library of 11,500 songs and found that only 15 were available as ringtones through the ITMS. Because of the novelty of it I decided to turn one of my favorite tracks into a ringtone through the "accepted" method. I chose Wilco's song Panthers. I paid my $1 and selected the 20 seconds I wanted. It worked great and still works. However, today I went on to see what other songs in my library were available as ringtones (hoping there were more). I was surprised to find that now I only had 5 songs in my library available as ringtones. Is iTunes reducing the selection of available ringtones? If so, why? Has anyone else noticed this?
