I am fan of this bollywood music service Saavn and I hear the same song whole day and sometime same song for days (latest one I am hearing is "Harry is not a bramhchari") as after a while the song doesnt matter and you can get into the coding gear.
Sometimes little little things on usability matter, I think they need to work on tooltips. I wanted to hear the same song in loop and I see no button for repeat and the green icon now looks intuitive that its a repeat icon once I have figured it out but initially it was not that obvious. So I did Inspect in firefox to figure out what is repeat button and what is shuffle.
So if you have just an icon toolbar you need to have tooltips for each icon. I just checked our storage file listing toolbar and luckily it has tool tips so the UX team has done a good job ;).
