In 1913, a composer named J.R. Shannon published a song titled "Good Old Denver Town," just one in a rash of Colorado-centric ditties that popped up on pianos in the early 1900s. Thanks to the CU-Boulder Music Library, 21st-century players can tune into the 150,000-plus treasure trove of titles written about D-town and beyond, plus a vast, timeless array of ragtime, Western and Ingram scores. Songs are accessible through the Digital Sheet Music Collection, an Internet database that's searchable by genre and title. Though the collection's primary mission is to preserve old-fashioned music from the player-piano days, the Digital Sheet Music Collection makes a great case for the beauty of life in the modern age.

A veritable museum of acoustic instruments, the Denver Folklore Center is stocked with used and vintage banjos, mandolins, dulcimers, autoharps and guitars from floor to ceiling; it's a sight to make the city's string players sing. A new generation of players can also find inspiration among the itty-bitty things for every skill level and hand size: whistles, tambourines, flutes, recorders and authentic Hawaiian ukuleles. There's also sheet music from around the world, instructional videos and CDs, stands and strings -- even those fancy harmonica neck-wrap thingies that really boost the average Dylan impression. Staffed by players, teachers and die-hard folk loyalists, the Folklore Center strikes the perfect chord.

Twist & Shout is planning to relocate from its current home as part of the ambitious Lowenstein Redevelopment Project -- but this news shouldn't concern longtime supporters of the store. Indeed, the expansive new space should help the Twist & Shout team provide even more of what's always made the store an oasis in a retail desert: great selection, the city's largest supply of CDs by local artists, staffers who are wired-in and totally approachable, and an atmosphere that's so comfortable you may want to move in permanently.

With the music industry's transition from platters to downloading proceeding at a frantic pace, shops specializing in used CDs are an endangered species. But SecondSpin.com is still here, and how. The firm's Denver branch is 12,000 square feet and offers a killer selection of more than 70,000 discs and 30,000 used movies. Moreover, the store is outfitted with the listening stations and other accoutrements that are common at places that sell new merchandise, but rare at businesses that peddle previously owned items. For folks who have not joined the MP3 generation and don't want to pay new-disc prices, SecondSpin.com offers a last chance.

Once upon a time, the competition for Denver's best vinyl haven was fierce -- yet Wax Trax usually came out on top. Today, most of the also-rans are history, while Wax Trax's vinyl branch remains. The reasons are simple: Wax Trax Vinyl inspires intense loyalty among knowledgeable collectors of LPs and 45s because of its great prices, cool selection, and staffers who know more about music than just about anyone in these parts. Simply put, it's a Denver treasure.

Let's face it: Denver's still pretty damn white -- a city with umpteen wine bars and rock venues but just a handful of halfway-decent jazz or hip-hop joints. Independent Records and Video -- the store with the big, beautiful display windows filled with big, beautiful photographs of African-American recording artists -- is one sign of urban life in D-town. The store carries an impressive selection of music in every genre -- it's the only place in town where you can satiate a midnight Big Star jones on a Tuesday -- but its primary trade is hip-hop and R&B. True, white kids could be the ones who are buying it all up, but who really cares? As the only storefront on Colfax to proudly represent black culture, Independent gets a big holla.
