Must have a Google Play account. Google Play and Merge Records celebrate Merge's 25th anniversary by making 25 songs available for download.
Artists include: Arcade Fire, She & Him, and Wye Oak.
If you know you want a song without listening to a sample, just click on the word "free" in the box with the song title and artist name. You then get the usual Google Play pop-ups to "purchase" the free song.
Or, if you want to hear a sample first, click on the song name and another page will display. Then, click on the track number to start playing a sample. If you want the song, click on the "free" button on the right to "purchase" the song. You'll have to use your back button to return to the list of songs.
Repeat as desired for the rest of the songs.
Warning: If you click on any price field that has a dollar amount in it, you will start the process to actually spend money. If there is a dollar amount, it's not free! The albums containing the songs are not free!
