INPUT ARTICLE: Article: The great thing about most apps and websites is that you can put the songs on shuffle, edit your playlist and add new music even when you're done, so you don't have to worry about the order yet. Nothing is set in stone, like on a CD or a mixtape. Start dumping all the songs you're considering including on the playlist in and worry about sorting them out later. Alternatively, you could go with the mixtape approach, and go one song at a time, carefully selecting the movement of the playlist. This is especially good for dance mixes of headphones mixes. Whatever your theme, genre, or taste, one thing about playlists is universal: it's got to start with a great song. Lead off with a song that'll hook everyone who'll listen, or will kick off your personal favorites playlist with a bang. Alternatively, maybe the order of the songs is predetermined (as in a countdown playlist) or maybe you're just not interested in a carefully selected order for the songs. Consider randomizing the order by hitting shuffle, or by tossing the songs in alphabetically for easy access. This tends to be easier for very long playlists. In most cases, you'll want an awesome playlist to vary the mood, the tempo, and the tones in the music somewhat, or else it'll get repetitive and dull. Even if you're making a Best of Black Metal playlist, try to throw some more atmospheric headbangers in there, or it'll be hard to follow. Alternatively, a party playlist should probably only go up, so start with a banger and progressively get rowdier. Likewise, a go-to-sleep playlist should stay relatively sedate. Let it fade off into white noise or silence at the ending. Some songs have abrupt endings while others will have gradual fade-outs or codas. Some rock songs end with long blasts of feedback, while other songs will fade out. Listen to how each song transitions into the next. Avoid aural schizophrenia. It's nice to have some variety, but going straight from Slayer to Simon and Garfunkel will sound strange. It's your playlist, but try to make the order relatively smooth. Slayer to Led Zeppelin's "Since I've Been Loving You" to Simon and Garfunkel? That's more like it. You can put your playlist on your phone, iPod, CD or any other portable music device like a flash drive and take it out with you on a run, or to the gym, or to the party where you want to dance and try it out. Delete songs that don't work and add songs that enhance the experience that you're soundtracking. If that Cat Stevens song wasn't as relaxing as you wanted it to be, delete it and go softer. It's easy to make changes.

SUMMARY: Dump everything into one playlist. Start with a hook. Include some highs and lows. Listen to the transitions. Test it out.


INPUT ARTICLE: Article: Look for chlorine solutions designed to shock your pool at your local pool supply store or online. Make sure it is safe for use on all pool types, including salt water pools. Make sure the chlorine and pH levels are correct in the pool. Check that the calcium, alkalinity, salt, and stabilizer levels are correct as well. This will ensure shocking the pool will not cause any staining or damage. Shocking the pool with chlorine is a good way to prevent the water from becoming cloudy and polluted if you are having a lot of people in the pool. It's also a good way to give your pool a deep clean once a year. For a standard size salt water pool, you may use 3 pounds (1.4 kg) of chlorine per 1,000 gallons (3,800 L) of water. Check the manufacturer's instructions if your pool is smaller or larger than the standard size. Make sure the filter system is working and the pH is between 7.2-7.4. Add the chlorine a small amount at a time around the edges of the pool. Let the chlorine dissolve into the pool water. Use a test kit to check the chlorine levels in the pool. Make sure the chlorine levels have dropped and the water is safe to swim in before you use the pool.

SUMMARY:
Get chlorine to shock the pool. Test the levels in the pool. Determine the right amount of chlorine. Add the chlorine a little at a time. Wait 8 hours and test the chlorine levels before using the pool.
