Streaming music service Spotify is offering college students in the US access to its unlimited, ad-free tier for $4.99 a month, half the usual price. The discount can be used with both new and existing Spotify accounts, and it's valid for twelve months at a time; student subscribers can reapply the offer each year for a total of three renewals. In order to get it, you'll have to submit a copy of a student ID card, transcript for the current term, tuition receipt, or some other document that proves you're at an accredited US institution. The terms and conditions specify that the discount is offered for a limited time while supplies last, but there's no sign that it will be ending any time soon.

Spotify has previously offered university discounts in the UK in partnership with the National Union of Students, and streaming music services have been heavily targeted at college students: Rdio dropped its price for them last year, and services like Rhapsody have previously been offered directly by colleges in an effort to deter piracy. On a larger scale, however, prices are more likely to rise as companies try to actually turn a profit. Earlier this month, Radio service Pandora raised its monthly fees and removed the annual subscription option, saying that increased licensing costs had made it unfeasible.
