fixes to work out of box on macOS Sierra itunes .m3u

[idcrook]

I needed to make a few tweaks for this to work "as advertised" on macOS, Python 2.7.13, with a .m3u file generated from iTunes playlist export on macOS.

The 'U' in the open statement stands for universal line ending support. The .m3u from iTunes has \r/^M as its line separator characters.

Found here: http://stackoverflow.com/questions/4158645/make-the-readline-method-of-python-recognize-both-end-of-line-variations

Don't have time to make real PR at the moment.
