GAANA.COM is a great site to listening any songs online.
the most I like about the is the design of the website. the dark theme is great. also nice the intro theme, when website loads.
very easy and free signup. u can sing up with your Facebook account, which make it very easy and user friendly.
many different language you can choose, like Marathi, Tamil, Telugu and Bhojpuri is noticeable among them.
They have a good collection in Hindi and English department. you can choose songs by artist, album, songs as you want. this make it very useful to find my favorite songs. also you can see overview, top chart, new release etc. audio quality is also good. you can make your favorite list and play when you want.
thank you.
