While it may be tempting to lament over the end of the holidays, it's best to face the facts: Vacations end, and you have to get back to work.
After all, your to-do list won't go away with neglect, and you'll feel better accomplishing tasks in a timely fashion. Fortunately, we put together a Spotify playlist to help motivate you to work.

1. To follow Mashable on Spotify, click here. If a popup window asks you to launch an external application, accept. This just means the browser will open up Spotify.
2. Follow Mashable, or send us music by clicking "Send Music."

3. To send music while browsing tracks within Spotify, follow the MashableHQ account. Then right-click (ctrl + click) on the song you want to send, and click the "Share" option.

4. By default, Spotify pulls up the "Post to Feed" option. Instead, select the "Send to Friend" tab, type in "MashableHQ" and hit the blue "Send" button.

If "MashableHQ" doesn't show up when you're trying to send a track, make sure you're following the account. If you're still having problems sending a song after that, let us know in the comments, below, and we'll help you fix the problem.
