Google Play Music is a pretty exceptional service that lets you import your entire music collection to a dedicated music cloud account. Once uploaded you have access to those songs on any device to stream, download or sync for offline listening. It is also where all your purchased music from the Play Store gets housed. Initially consumers were able to upload up to 20,000 tracks. Google would in turn give them album covers and even exchange lower quality versions for the highest quality version they had on hand for your. Heck, they even swap your tunes after they analyze the tracks and just make them instantly available if they already have the tunes on hand. Needless to say it is a great way to have your tunes accessible at all times.
Now Google is raising the song limit from 20,000 tracks to a whopping 50,000 tracks. Best part, it is still all free for you to do this. No need to worry about a monthly access fee to access your own tracks on the go. There isn’t any special trick needed to gain the extra space, just simply head over to your Google Play Music account and log in. You may not see the limit increase on the main upload page, but it is listed on the Music Manager download page and displays how many tracks are left in your limit when uploading through the Music Manager app.
